FBR......if I am around my roommate for about 5 sessions a week lasting about 5-10 minutes with the window open and a small fan blowing in the living room, do you think I am cracked out when I think I could slowly be accumulating small amounts of thc in my body?

Taking into account I am around the smoke maybe 5 times for 5 minutes a week, with the window open and fan on, what do you think my ng/ml would be on a GC/MS test. I know this is tough for you to estimate on, but do you think my levels are real low (10 ng/ml), or might they have risen over time and consistency of exposure?

I know Storm Crow sort of touched on this, but I was just curious to get your opinion if you wouldn't mind. Thanks much.
