Haha.

First off, not all illegal drugs show up. Some can't even be tested for.

NIDA 5 is the most common test given, and tests for 5 substances. Cannabis, meth, pcp, coke, and I think opiods. You can look up "NIDA 5" though and find out for sure.

Weight pills though? What were they?

They could test her positive for something...were they stimulants? Maybe they could trigger a positive for speed or something.

She's a ditsy blonde, but I found the question hilarious. I called her when I read it and was like what did you take? She's like some weight pills she doesn't think are legal. I'm glad I was stoned when I called her cause it was funny as fuck. Happy toking. :rastasmoke: Rating: 5
