IF I took Adderall a few times in the month of may and have a hair follicle test coming up, (June 11) what are my chances of failing? Nothing else for 7 months.

Assuming, they test for that. (not all tests , test for everything) and assuming, it was only a few (that means 3 times) not 20 times or 12 times.

You should pass.

I could make this a complicated explanation but I'll skip that and guess you will be negative, mainly due to the steps the hair goes through when it is tested at the lab. Also I don't think that is enough usage to show in a hair drug test. A hair drug test is meant to show consistent use over time. If it was just "a few times" again I say it will be negative.

Even if your small usage is detected at all, you probably fall under the fail level.
