One sign only: A doctor has precribed a benzo for daily use, as it is most often prescribed. The patient - using it only has directed - has been on it for 4-6 weeks. He or she is now hooked. Simple as that.
How long before a person is chemically dependent on klonipin 1 week 2 or a month
Addiction wise is different but how long can you take klonipin before quiting. I would estimate if you are taking it at least 1 a day that maybe 2 weeks you'd experience side effects from coming off of it. Obviously there's variables like if you taper the medication before disuse, the dosages and frequency, any other meds, etc.
I have seen these signs with a close friend. It takes a long time to find the signs or admit to yourself, especially if it is someone you love a lot.
