I took a hair follicle test yesterday

Hey all!

So yesterday I took a hair follicle test and I've been stressing out about it for a long time. The last time I smoked pot was around the middle of February, or the beginning of March. I only took one hit. The time before that was a few weeks before and I took one hit from a joint. I keep my hair very short and I cut my hair probably 3 weeks ago. It's no longer than 3/4" right now and that is what they used to cut, and send off to the lab.

I have heard an inch and a half is 3 months, so I am thinking what they took might just be a month and a half...

I am 170 lbs., I play basketball everyday for hours, and drink tons of water...if that has anything to do with it. Also have lightish brown hair.

Do I have a chance at passing?
