I was goofing off the other day and found my old bowl (unused for 9 months) in a closet. I put it to my mouth and then inhaled it, unlit. I then realized that I have to take a drug test tomorrow, and I'm worried that I got THC in my lungs. I haven't smoked for 9 months, and when I last used the pipe, I didn't have any more marijuana so I just lit the resin in the pipe until it didn't affect me anymore, so I'm thinking that I may have burned out the THC months ago in addition to time maybe making it less potent. I am freaking out about this, and I really don't want to have to use a detox drink since I haven't done anything for so long. I've heard that small amounts of second hand smoke won't appear in a urine test, and I maybe the small amount of THC that may have gotten in my body would go under a threshold or something. Please help!

Probably not, but if you want to know for sure you can buy a home THC test. Wal-mart used to sell them, I am not sure if they still do.
