Both home drug tests have been negative. Are otc drug tests specifically for thc in the $15-30 price range reliable?

Subbing is not a problem, but I am a little scared of getting caught.
hc526 Reviewed by hc526 on . Drug tests and pregnancy I have read a number of the threads and haven't one related to pre-employment drug testing and pregnancy. My question is in regards to dillution, can I use N2s advice and skip the aspirin? Currently smoking 1x a wk between 1-3 hits. I have a drug test coming up for a new job. I can hold off for about 5 days or so. It will be 8 days at that point from taking 1 hit and 2 wks from taking a few more. I am 5'3" and 6 months along. Currently 144lbs, however was always 118-122 with a high metabolism. Rating: 5
