If a man on drugs......?

Immediately following fluid exchange the partner could indeed test positive for drugs. As all bodily fluids (saliva, urine, blood) can be screened for drugs, semen most definitely can be as well. Condom use would of course eliminate(you hope) semen in the woman, but without a condom you might be stuck.

I know for a fact that this would occur only if the exchanged bodily fluid is the tested material. Meaning after deeply kissing someone who had recently used drugs, you would test positive on a saliva drug test. I don't know for a fact that you would then also test positive in a blood test. Hope this helps.

I was pretty paranoid once that I wasn't going to pass a drug test when I was dating someone who was a heavy user. They did a saliva test though, right after lunch. I'm not convinced that anything would've shown on this thing unless one was using their lunch break to hit their crack pipe.

lol that is a good question, but i dont think so the sperm wouldnt absorb into the girls bloodstream(dog is awesome)

Probably not otherwise she would feel some effect too especially if she does oral and swallows (not to be gross or anything).

It might.

But either use a condo or *** on her face

yea that would be a trip ... good thought

I don't take any drugs :p.........

probably
