A 23-year-old female asked:

Many people have self reported to test positive for a urine drug test (like cocaine & meth) after having sex with their partner because drugs can transfer through semen and sweat. would thc also create positive test results even if they dont smoke?

Second hand smoke: Second hand smoke from weed is more likely to cause you to have a positive urine test for THC than any transmission through semen. I doubt the explanation of people blaming semen for positive drug test. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV vaccine.
