Drugs will be filtered at the kidneys and excreted in urine. However, urine is held at the bladder until a signal to relax is sent (during urination). So I don't see how it can jump to the other person. Assume that it does spit into the air (!!!!), it can't get into the person's body unless it travels through his/her oral cavity. If by chance, it gets into the other person through "that" contact, it should be minimal and the body will act to get rid of it. Sexually transmitted diseases got their names because the acting organisms can invade the reproductive system. I'm not too sure about drugs in general. The rectus (the other opening) is continuous with the gastrointestinal tract which shouldn't have much of the drugs or at all because they're meant to be absorbed into the circulation to exert their effects. Again, we're just looking at possible tranmission pathways in a sexual intercourse. I will say no but I will ask my lecturer when I have the chance because it involves chronic drug use which maintains the drug concentration in the body, so it may do other things I can't think of or actually know of, given my limited knowledge.
