The only drugs that are found in semen are certain chemicals found in psychoactive abuse drugs. So far no other drugs in sperm will cause a positive drug test. A hair follicle test will test positive for drugs much longer than the other tests. Stay away from those who can cause problems and practice safe sex.

If the child was not directly exposed to the smoke, the child is not likely to test positive. Wish you and your child good health!
