It's definitely not the issue - the issue is the bans ultimately steal everyone's time because we have to spend several months on compliance and preparations for something that would take just days otherwise. Any new regulation steals more time just because people need to learn and apply it and other people to enforce it etc. etc. It slows down the whole system and make it more bloated and expensive rather than streamlining it and making it more efficient.

You can actually separate the nitrite with just aqueous chemistry: Wash the salt mixture several times with a small amount of cold water - repeat the washes until it tests negative for the presence of nitrite (e.g. Griess test or starch + acidified potassium iodide). Combine the washes. Add 1 equivalent (w.r.t. nitrite) sodium hydroxide solution. If nitrate is present, it may precipitate as sodium nitrate and can be separated from mother liquor by filtration. Add 1/2 equivalent calcium chloride soluton. This will precipitate nitrite in the form of calcium double salt: 2 NaNO2 + 2 NaOH + CaCl2 + H2O → Ca(NO2)2 • Ca(OH)2 • H2O + 2 NaCl Note that calcium nitrite is a weak base because the nitrous acid, unlike nitric acid, is a weak acid (pKa_HNO2 = 3.25). Hence its conjugate base (nitrite) has pKa_NO2 = pKw - pKa_HNO2 = 10.75, making it weakly basic. The calcium ion is too weak of an acid (pKa_Ca = 12.6) to compensate the basicity of nitrite. Addition of calcium hydroxide (formed in-situ from calcium chloride and sodium hydroxide) causes precipitation of calcium nitrite by means of stronger base (hydroxide) and by the common-ion effect (added calcium ions). The double salt can be separated by filtration and hydrolyzed using sufficient amount of clean water. A solution of sodium or potassium nitrite can be obtained by adding respective carbonate salt - calcium will precipitate while the desired salt will stay in solution: Ca(NO2)2 + Ca(OH)2 + Na2CO3 → 2 NaNO2 + CaCO3 + Ca(OH)2 Note there is still calcium hydroxide lingering. It can be removed by adding sodium bicarbonate rather than carbonate - this will neutralize the hydroxide resulting in carbonate and water: Ca(NO2)2 + Ca(OH)2 + 2 NaHCO3 → 2 NaNO2 + 2 CaCO3 + 2 H2O If just calcium nitrite is desired, the hydroxide can be removed by adding calcium bicarbonate or ammonium carbonate. The latter requires cold solution as ammonium nitrite is very unstable (!): Ca(NO2)2 + Ca(OH)2 + Ca(HCO3)2 → Ca(NO2)2 + 2 CaCO3 Ca(NO2)2 + Ca(OH)2 + 2 NH4CO3 → Ca(NO2)2 + CaCO3 + 2 NH4OH NH4OH ⇌ NH3 + H2O

We were given and used Methylene chloride to clean fiber optic strands before spicing in Washington D.C. in the phone companies fiber optics group. I remember when management came out one morning and mangers physically removed every vile from our trucks.
Nice video! Love the Soxhlet attempt, definitely something I could see myself trying. Interestingly enough I did something similar to this once, but I never put out a video on it because it the procedure was so absurd. Basically got rid of 90-ish% of the chloride ions by precipitation with lead nitrate, then added silver nitrate to the remaining solution. Silver precipitated out the remaining chloride and silver nitrite has a very nice solubility curve for easy recovery (20g/L @100C and 1.5g/L @0C). Got 13 or so grams of pure silver nitrite from 100g of curing salt.
I marvel at the complexity of chemical reactions, there implications and practical uses. It should be taught in schools like I see it on youtube just for general education for those that have little inclination to pursue it or do not have the ability to understand the full complexity of these reactions. It would be like knowing how to change a wheel on a car without understanding what makes it turn.
the yellow in the flame comes from Sodium, that is burnt. the sodium comes from glass. to see the clear flame you should try burning it on surfaces that don't contain sodium.
I know about sodium, but that's not the cause of the yellow here (which was actually more white than yellow). It's simply due to the higher carbon content, which is also why methanol burns with a dim blue flame and isopropanol burns with a similarly white-yellow flame.
It’s not “A few” it’s been hundreds, quite a few kids. Also a certain website pushed this method as preferable to others and even gives access to sellers, so there are people knowingly making money off suicide and the only way to prosecute them is making the chemical illegal.
Keep the reaction down around 2 F to -5 F. Jackedted reactor or shaved ice packed with salt will work well. Distillation under reduced pressure is also suggested.

YES! but also, just upgrade your amazon account to a business account, (which is really easy to do) and you can then order lab grade NaNO2 directly to your house! I'd know cuz I have to run a bunch of sandmeyer reactions to sustain by "research" of gamma butyrolactone.
and i don't know if DCM is banned, or rather just heavily restricted and regulated. I just successfully ordered 5 gallons of it to my house. Stay Safe! Happy Travels!
Amyl nitrite is supposed to have an auto ignition temperature of only 205C. Ethyl nitrite is said to have an ignition temperature as low as 90C. I’m not sure what it is for isopropyl nitrite but I assume it’s also much lower than for ordinary volatile hydrocarbons, alcohols etc.
Cool compressed air at ~1MPa, being released by a rupture disk might be able to ignite organic nitrite vapor (initially at room temperature and atmospheric pressure) by shock heating alone.
Consider trying to make nitrates via the nitrogen cycle, which is really common thing to deal with in the aquarium world I believe if you filled an IBC tote full of something like polyurethane foam, like mattress foam, and had it circulate with a bubbler, you could convert significant quantities of protein materials, perhaps beans, into nitrate. Removing it from all the water would be tricky but doable via some sort of evaporation pond or DIY drum rotary evaporator/dehydrator.
Is there a reason to use 91% isopropyl alcohol over 99%? I was able to find 99% online pretty easily and I think 99% seems noticeably more effective than 91% at cleaning... certain plant based resins... from glassware (lol). I wonder if the higher concentration would be helpful in your applications, too.
i dont think it would be banned that much. maybe highly regulated. meat processors loves this chemical so much, its litterally all in one for sausages and such (antibio antioxy conservator and effing dye)
Note: While sodium nitrite is safe you REALLY want to be careful with any alkyl/amyl nitrite (isopropyl nitrite included). Any degree of any type of contact with liquid or vapors is dangerous.
actually the vapors in reasonable quantities are fine - skin contact with the vapors is negligible at most, and breathing them in won't be a big issue either as long as you don't suffocate yourself with them. Prolonged contact with the liquid can cause very minor burns in sensitive areas around the nose or mouth, but IME durable skin such as fingers, arms, etc. don't experience much irritation at all. Ingestion should be avoided AT ALL COSTS, and if you suspect you swallowed alkyl nitrites, get medical help right away. Best case they moniotr you and end up giving you the all clear, worst case your SpO2 continues to drop, and they save you via methalyne blue.
@@projectisaac - What? The vapors are used as a recreational drug they are so intoxicating. General hazards listed on Pubchem as well as a ton of articles on their dangerous uses.

What if the salt mixture would be disolved in water, boiled down, cooled so that a part of the sodium chloride crash out and repeated until a reasonably concentrated solution of sodium nitrite remains that can be evaporated and used as it is or purified with ethanol? It would be fairly low-tech procedure that can process larger amounts or salt mixture. It's like NurdRage's video about making potassium chlorate out of bleach when he boiled down the sodium chlorate solution to get rid of sodium chloride.
Hello. I was just wondering how much chirality plays into your chemistry life. Once again.....i'm trying to get through this amazing barrier in being able to conceptualize it and understand and to make sense of diastereomers, enantiomers and all that stuff. Thanks.
Cant you make nitrite by electrochemical reduction of very soluble AgNO3 to slightly soluble AgNO2 and than reacting AgNO2 with NaOH to make NaNO2 and AgOH the AgOH can be reusel by reaction of nitric acid and the NaNO2 can be crystalized by boiling of the water
You can get sodium nitrite as "chemical tungsten sharpener"...but then they might start only selling it to companies with a valid tax number and for you to sign a legally binding end use certificate. And it's ridiculously expensive.
Nitrite salt in my neck of the woods contains about 0.6 % nitrite, so about one tenth of the mass fraction of your salt. This will make it much less viable.
Well, the cat's out of the bag now! Thanks a bunch, LabCoatz! You've just handed legislators the perfect blueprint for adding yet another restriction to sodium nitrite. Who knew a simple curing salt could become public enemy number one? Way to go, buddy-now they’ll probably ban Thanksgiving hams just to be safe! 😂😂😂😂
I wonder if it would be feasible to simply use boiling down to remove sodium chloride and then recrystalize, exploiting the steeper solubility curve of nitrite?
It wasn't really a sodium-orange flame color, it was more of a yellow-white color similar to what you get if you burn regular isopropanol. It's most likely from the higher carbon content of the molecule: nitromethane has only one carbon, so it is closer to being oxygen-balanced, while isopropyl nitrite has three. If this was something like octyl nitrite, it might even produce soot when burned!
My understanding is the nitrite salts react with some amino acids to form nitroso- compounds, which eventually become carcinogenic diazo compounds during metabolism. The effect is apparently more pronounced when the meat is browned, I think the maillard reaction pushes it along? I don't think the nitrite itself is carcinogenic, but bacon 100% is, unfortunately.
can you do curing salts to high concentration (not fuming) nitric acid ? can you denitrite a explosive to get nitrogen ? like reverse TNT back to tuloene and nitrogen?
i see how you are comparing the LD50 for the deadliness of DCM, i personally dont like working with it because of the highly carcinogenic aspect of it lol
ive used nitrates directly with isopropanol in an electrolysis setup to obtain isopropyl nitrite. 9v battery or a few aa's tossed inside the beaker will do the trick 😂
What does the long term storage of isopropyl nitrite look like? I would imagine it would be stored anhydrous in the dark, but eventually I would assume it offgasses a lot? Should it be treated just like 68% nitric acid? Or is it worse of a chemical (or vice versa)?
It doesn't seem to be too sensitive. I just store it in my garage, which regularly gets above 30-40C. It does degrade slightly, so NOx may be released.
@@LabCoatz_Science I carried out a synthesis after ur video but with a bunch of other different alcohols (butanol, propanol, isopentanol, pentanol, cyclohexanol) and purified them with fractional/fractional vacuum distillation, and it seems that the larger an alcohol is, the faster it decomposes. I stabilized everything with roughly 50/50 mixture of sodium sulfate (prevent hydrolysis) and sodium carbonate (buffer to prevent acid catalyzed hydrolysis), along with a bit of BHT (prevent radical decomposition), and stored in a cool dark basement. After coming back 2 weeks later, the cyclohexyl nitrite had decomposed significantly since the stabilization salts were clumped up and orange, while the smaller nitrites like n-propyl or isopropyl nitrite showed no sign of decomposition. However I would imagine that alkyl nitrites on the long term are quite unstable and prone to degradation, so i would not recommend long term storage and just prepare it when you need it for say sodium azide or any other synthesis etc.
DCM is about as deadly as acetone...well maybe not, but there's a lot of OTC products that are far worse, like gasoline. It's super weird how they classify or justify some things. Iodine was highly regulated in the early 2000's if I recall, and the reasons I heard (may not be true at all) were because it was used by some unsavory ppl for unsavory reasons, but I don't think anyone ever actually did, they were just over correcting for something that wasn't actually as big of a problem as they reported.
With what's going on at YT regarding all the Yosemite Sams right now, I really feel like Chemistry is next. ): It's just the sad natural progression of events from here.
Isopropyl nitrite is also the chemical name for the party drug known as poppers. It gives you a euphoric head rush as well as relaxing a lot of smooth muscles in your body. This is the reason it has gained popularity among gay men, due to how it facilitates anal sex. Also, the exact effects and duration of the nitrite is dictated by the length and branching of the carbon chain. Short chains and highly branched chains like isopropyl or isoamyl nitrite have a much more intense effect, but a shorter lived effect. Longer and straighter chain nitrites have a longer duration effect but are typically weaker.

I can agree with the Dichloromethane ban because it is carcinogenic, but it’s also dangerous because of its very low odor.
please get this chemist to 100k PLEASE
We were given and used Methylene chloride to clean fiber optic strands before spicing in Washington D.C. in the phone companies fiber optics group. I remember when management came out one morning and mangers physically removed every vile from our trucks.
yeah i need amyl nitrite for an upcoming "project"..... :3
Btw it's pronounce like 'prog', like the city
Nice video! Love the Soxhlet attempt, definitely something I could see myself trying.
Interestingly enough I did something similar to this once, but I never put out a video on it because it the procedure was so absurd. Basically got rid of 90-ish% of the chloride ions by precipitation with lead nitrate, then added silver nitrate to the remaining solution. Silver precipitated out the remaining chloride and silver nitrite has a very nice solubility curve for easy recovery (20g/L @100C and 1.5g/L @0C). Got 13 or so grams of pure silver nitrite from 100g of curing salt.
I wonder if Labcoatz is planning on making "Substance-N"?
Someday. I have to make fluorine first!
@@LabCoatz_Sciencemmm fluorine 😋
I marvel at the complexity of chemical reactions, there implications and practical uses. It should be taught in schools like I see it on youtube just for general education for those that have little inclination to pursue it or do not have the ability to understand the full complexity of these reactions. It would be like knowing how to change a wheel on a car without understanding what makes it turn.
the yellow in the flame comes from Sodium, that is burnt. the sodium comes from glass. to see the clear flame you should try burning it on surfaces that don't contain sodium.
I know about sodium, but that's not the cause of the yellow here (which was actually more white than yellow). It's simply due to the higher carbon content, which is also why methanol burns with a dim blue flame and isopropanol burns with a similarly white-yellow flame.
It’s not “A few” it’s been hundreds, quite a few kids. Also a certain website pushed this method as preferable to others and even gives access to sellers, so there are people knowingly making money off suicide and the only way to prosecute them is making the chemical illegal.
I’m saying this as a chemist
What a great talk Mike, respect.
Keep the reaction down around 2 F to -5 F. Jackedted reactor or shaved ice packed with salt will work well. Distillation under reduced pressure is also suggested.
Nobody can stop you from making a Birkeland-Eyde reactor. Plus, its pretty fun!
That was actually the topic of one of my first videos!
@@LabCoatz_ScienceBrothers, in our country, senior officials often use their positions to sexually assault female subordinates. Is there a drug to protect women, so that those who want to sexually assault lose their sexual ability and cannot get up for a short period of time, so as to protect women?
YES! but also, just upgrade your amazon account to a business account, (which is really easy to do) and you can then order lab grade NaNO2 directly to your house! I'd know cuz I have to run a bunch of sandmeyer reactions to sustain by "research" of gamma butyrolactone.
and i don't know if DCM is banned, or rather just heavily restricted and regulated. I just successfully ordered 5 gallons of it to my house.
Stay Safe! Happy Travels!
Prague powder sounds like a traditional chinese medicine.
Amyl nitrite is supposed to have an auto ignition temperature of only 205C. Ethyl nitrite is said to have an ignition temperature as low as 90C. I’m not sure what it is for isopropyl nitrite but I assume it’s also much lower than for ordinary volatile hydrocarbons, alcohols etc.
Cool compressed air at ~1MPa, being released by a rupture disk might be able to ignite organic nitrite vapor (initially at room temperature and atmospheric pressure) by shock heating alone.
Is there a simple way to just split the NaNO2 off from the salt?
Consider trying to make nitrates via the nitrogen cycle, which is really common thing to deal with in the aquarium world I believe if you filled an IBC tote full of something like polyurethane foam, like mattress foam, and had it circulate with a bubbler, you could convert significant quantities of protein materials, perhaps beans, into nitrate.
Removing it from all the water would be tricky but doable via some sort of evaporation pond or DIY drum rotary evaporator/dehydrator.
Nice... I have faith that you'll find a method that will yield more than 52%
sometimes i think politicians should have to get qualifications before they can be in charge of overseeing stuff or being put in charge of things
Is there a reason to use 91% isopropyl alcohol over 99%? I was able to find 99% online pretty easily and I think 99% seems noticeably more effective than 91% at cleaning... certain plant based resins... from glassware (lol). I wonder if the higher concentration would be helpful in your applications, too.
i dont think it would be banned that much. maybe highly regulated. meat processors loves this chemical so much, its litterally all in one for sausages and such (antibio antioxy conservator and effing dye)
Note: While sodium nitrite is safe you REALLY want to be careful with any alkyl/amyl nitrite (isopropyl nitrite included). Any degree of any type of contact with liquid or vapors is dangerous.
Safe unless you ingest a hundred grams at once.
Only dangerous if you chug the video head cleaner like it's 5 Hour Energy, or decide to sniff it while you're drunk or taking Viagra.
actually the vapors in reasonable quantities are fine - skin contact with the vapors is negligible at most, and breathing them in won't be a big issue either as long as you don't suffocate yourself with them.
Prolonged contact with the liquid can cause very minor burns in sensitive areas around the nose or mouth, but IME durable skin such as fingers, arms, etc. don't experience much irritation at all.
Ingestion should be avoided AT ALL COSTS, and if you suspect you swallowed alkyl nitrites, get medical help right away. Best case they moniotr you and end up giving you the all clear, worst case your SpO2 continues to drop, and they save you via methalyne blue.
@@projectisaac - What? The vapors are used as a recreational drug they are so intoxicating. General hazards listed on Pubchem as well as a ton of articles on their dangerous uses.
Ok straightie
Someone may have already said this, but I'm almost certain you say "Prague Powder" in the same way you'd say the name of the Czech capital city "Prague"

Well, I enjoyed your channel. You had a good run.
The Government needs to stop banning things and let Darwin handle it.
Darwin will handle it eventually anyway, don't worry 🦥 🙂 Fortunately the laws of nature are above any written laws - yes they can ban gravity, but, well... try to enforce that :)
Imagine if a suicidal person read this? It could really hurt them
What if the salt mixture would be disolved in water, boiled down, cooled so that a part of the sodium chloride crash out and repeated until a reasonably concentrated solution of sodium nitrite remains that can be evaporated and used as it is or purified with ethanol? It would be fairly low-tech procedure that can process larger amounts or salt mixture. It's like NurdRage's video about making potassium chlorate out of bleach when he boiled down the sodium chlorate solution to get rid of sodium chloride.
Hello. I was just wondering how much chirality plays into your chemistry life. Once again.....i'm trying to get through this amazing barrier in being able to conceptualize it and understand and to make sense of diastereomers, enantiomers and all that stuff. Thanks.
What is the explosive chemical he is talking about making
Think carbon tet but with azide groups...
Great video. Thanks for sharing
Cant you make nitrite by electrochemical reduction of very soluble AgNO3 to slightly soluble AgNO2 and than reacting AgNO2 with NaOH to make NaNO2 and AgOH the AgOH can be reusel by reaction of nitric acid and the NaNO2 can be crystalized by boiling of the water
Or use Pb(NO3)2 this is cheaper and Pb(NO2)2 is lessen soluble compared to AgNO2
Maybe, I'd have to look into it.
Both those methods sound fume hood worthy.
At this point I`m pretty sure you be cooking MDMA on a side quest lmao
we use potassium nitrid as meat curing salt, mixed with Sodium chlorid.
You can get sodium nitrite as "chemical tungsten sharpener"...but then they might start only selling it to companies with a valid tax number and for you to sign a legally binding end use certificate. And it's ridiculously expensive.
Nitrite salt in my neck of the woods contains about 0.6 % nitrite, so about one tenth of the mass fraction of your salt. This will make it much less viable.
Thanks for the great video. Now to isolate the sodium nitrite another way ;)
Well, the cat's out of the bag now! Thanks a bunch, LabCoatz! You've just handed legislators the perfect blueprint for adding yet another restriction to sodium nitrite. Who knew a simple curing salt could become public enemy number one? Way to go, buddy-now they’ll probably ban Thanksgiving hams just to be safe! 😂😂😂😂
I wonder if it would be feasible to simply use boiling down to remove sodium chloride and then recrystalize, exploiting the steeper solubility curve of nitrite?
Do you work on Tetraazidomethane? (1 Carbon, 12 Nitrogen)
That's the plan.
@@LabCoatz_Science Love it! ❤
@@LabCoatz_Science Ho-ly shit.
Very cool reaction
Heat potassium nitrate until it melts and finishes liberating oxygen. You then have potassium nitrite.
Prague powder is banned in my country unless you have a bussiness that requires it.
Do not tell me about ban. I was going to start a trade business on some chemical species years ago. Today I would have failed because of bans.
Seems like running the pink salt in a Soxhlet with solvent would be the easiest, assuming you have one around.
That was my thought too, not sure how expensive they are though.
That's what I did, but it wouldn't cycle properly.

Orange color may be due to sodium contamination, tiny amounts can deeply color a pale colored flame.
It wasn't really a sodium-orange flame color, it was more of a yellow-white color similar to what you get if you burn regular isopropanol. It's most likely from the higher carbon content of the molecule: nitromethane has only one carbon, so it is closer to being oxygen-balanced, while isopropyl nitrite has three. If this was something like octyl nitrite, it might even produce soot when burned!
We can make anything we want. We actually prove it everyday.
What is the connection between sodium nitrates and stomach cancers?
California 😂
My understanding is the nitrite salts react with some amino acids to form nitroso- compounds, which eventually become carcinogenic diazo compounds during metabolism. The effect is apparently more pronounced when the meat is browned, I think the maillard reaction pushes it along? I don't think the nitrite itself is carcinogenic, but bacon 100% is, unfortunately.
@@BiglyWeenis Interesting
“We figure it out” Terrence McKenna
can you do curing salts to high concentration (not fuming) nitric acid ?
can you denitrite a explosive to get nitrogen ? like reverse TNT back to tuloene and nitrogen?
Re: your first try at extraction - would a Soxhelet extractor work?
That's what I tried to use in the video, but the liquid had trouble filtering through all the salt grains, so it wouldn't cycle properly.
Maybe a filler like molecular sieves to prevent the salts from sticking together?
I see it now. Thanks. I’m just some doofus who watches chemtubers. But I’m glad I had the same thought as someone who knows what they’re doing.
I won't be doing this, but I'm still curious... Is the salt left over, still viable for consumption? (after the acid is removed, of course)
R.I.P.
Ive a question , what do you mean by when you say , u get projects and what are they about and how do you get it?
I’m wondering if the orange/yellow color in the isopropyl nitrite flames was due to isopropanol that came over with the nitrite in the distillation
At first I thought it could be sodium ions bc it definitely seemed like the right color but that shouldn’t distill over at all
Thought you were going to make amyl nitrite
What holster due you use?
i see how you are comparing the LD50 for the deadliness of DCM, i personally dont like working with it because of the highly carcinogenic aspect of it lol
That's a good reason, lol.
Good job!
PV= nRT Reaction mixtures must never be closed (without a vent). Otherwise you have a bomb and need a pressure vessel.
So glad this is a thing. I always knew you could get nitric acid from cured meat haha
ive used nitrates directly with isopropanol in an electrolysis setup to obtain isopropyl nitrite. 9v battery or a few aa's tossed inside the beaker will do the trick 😂
Nice chemical labels! Did you make those?
Yup!
What does the long term storage of isopropyl nitrite look like? I would imagine it would be stored anhydrous in the dark, but eventually I would assume it offgasses a lot? Should it be treated just like 68% nitric acid? Or is it worse of a chemical (or vice versa)?
It doesn't seem to be too sensitive. I just store it in my garage, which regularly gets above 30-40C. It does degrade slightly, so NOx may be released.
@@LabCoatz_Science I carried out a synthesis after ur video but with a bunch of other different alcohols (butanol, propanol, isopentanol, pentanol, cyclohexanol) and purified them with fractional/fractional vacuum distillation, and it seems that the larger an alcohol is, the faster it decomposes. I stabilized everything with roughly 50/50 mixture of sodium sulfate (prevent hydrolysis) and sodium carbonate (buffer to prevent acid catalyzed hydrolysis), along with a bit of BHT (prevent radical decomposition), and stored in a cool dark basement. After coming back 2 weeks later, the cyclohexyl nitrite had decomposed significantly since the stabilization salts were clumped up and orange, while the smaller nitrites like n-propyl or isopropyl nitrite showed no sign of decomposition. However I would imagine that alkyl nitrites on the long term are quite unstable and prone to degradation, so i would not recommend long term storage and just prepare it when you need it for say sodium azide or any other synthesis etc.
DCM is about as deadly as acetone...well maybe not, but there's a lot of OTC products that are far worse, like gasoline. It's super weird how they classify or justify some things. Iodine was highly regulated in the early 2000's if I recall, and the reasons I heard (may not be true at all) were because it was used by some unsavory ppl for unsavory reasons, but I don't think anyone ever actually did, they were just over correcting for something that wasn't actually as big of a problem as they reported.
A better name for azidoazide azide would be isocyanogen tetraazide
With what's going on at YT regarding all the Yosemite Sams right now, I really feel like Chemistry is next. ): It's just the sad natural progression of events from here.
Isopropyl nitrite is also the chemical name for the party drug known as poppers. It gives you a euphoric head rush as well as relaxing a lot of smooth muscles in your body.
This is the reason it has gained popularity among gay men, due to how it facilitates anal sex.
Also, the exact effects and duration of the nitrite is dictated by the length and branching of the carbon chain. Short chains and highly branched chains like isopropyl or isoamyl nitrite have a much more intense effect, but a shorter lived effect. Longer and straighter chain nitrites have a longer duration effect but are typically weaker.
