Had not smoked for 3 years then smoked for a couple of months. Have not smoked for 123 days had to take a 90 day hair folic test from psychemedic using arm pit hair. Hair grows at an average to above average rate. What are the chances of passing?

If you smoked regular for 3 months, yes it will show up

What if you have not smoked since the use in 123 days will it show in the 90 day test

Unfortunately for you a hair test using body hair goes back about 9-12 months. The growing cycle for body hair is a lot slower than head hair. My best guess is that you might have some trouble passing a body hair drug test.
