"As hair grows out, any drugs used are encased in the hair shaft, so the longer the hair, the longer back in the individual's drug history the lab can detect. Most legitimate testing facilities, however, only use hair within about 3-5 cm of the scalp, and discard the rest. This limits the detection history to about 90 days, depending upon the rate of growth of the individual's hair."
All drugs will stay in your hair up to 90 days, with the exception of alcohol (12 hours) and LSD (unknown).

The test will go back as long as your hair is. Five months hair should be about 2 inches. Get three cut off to be sure.

You should just not do drugs,its not worth losing everything you have and you wont have to worry every time you need to do a test.and yes they can tell unless you cut about 3" off.because that's about 5 months growth

I'm afraid so.....I do believe that it goes back like 5 or 10 years...
A long time anyway...
Good luck, for whatever reason you asked this question....
