Hi all, I smoked marijuana about two months ago, then again about three weeks ago- all pretty small amounts. Before that I was completely clean. What are the odds of me passing? My hair is about 1.5 inches. Any helpful info?

Hair test, I forgot to mention.

Dr Bill is no longer answering questions on this, or any other, site.

Oh yikes. Do you have any insight

What do you stand to lose if you fail?

A job.

If it was twice and it was a "small amount" like you claim, you will probably be ok.

You may pass -But what happens next time?

A hair drug test is meant to show consistent use over time. A 1.5 inch sample of hair, cut at the scalp line, will go back 90 days. It depends on which hair drug test they use when they test you. IF they use the lowest limits of detection test (LOD) you might have some trouble passing. If they use a basic hair drug test you have a better chance of passing because the cut off levels for the basic hair drug test are higher, which means you can do a small amount of drug and still be negative. If it is a test for employment they usually use a basic hair drug test so at this point I would say your chances of passing are about 60%, just a guess.
