weerezcc8

I quit smoking a year and a half ago so I'm not worried about that, but I have a hair test in a few weeks and being a college student have been around friends who are smoking/at parties with smoking a few times throughout the last 8 months, most recently last week. Our dorm rooms don't have great ventilation but we didn't hotbox the rooms either by any means, never was the smoke visible as we vented somewhat out the window. I was able to smell it, but don't know what exposure I need to get any thc in my system.

My question, because there is so much varying information, is whether second hand smoke still contains thc and if so how extreme of exposure is needed to reach the cutoff. Also, my hair is about 1.75 inches.

Thanks.
