THC in Semen? [Ask Dr. Miro: What You Didn’t Learn In Health Class]
Dear Dr. Miro,
My boyfriend smokes a lot of weed and we don’t use condoms. I have a drug test next week. Can I test positive for THC from him coming inside me?
If testing positive for THC from ejaculate intake was possible, there would more than likely be a Seth Rogen film with that as a sub-plot. THC is short for Tetrahydrocannabinol, which is the principle psychoactive ingredient in cannabis. We have all heard of the false positives for opiates after eating a poppy seed muffin and so the silence on this matter pushes me to the conclusion of NO. As this is not a good method for reaching scientific conclusions, I began further research.
Amielle Moreno, a Seattle based Research Scientist, had this to say, “Let’s go over facts: THC is fat solvable and it’s also found in hair which is protein. Semen includes a large amount of protein, but the amount of THC in semen would be negligible. The THC has already been processed by one person before it gets in contact with a vagina, mouth or rectum. I don’t think it would be enough to test positive.” Since fats are processed through an entirely different system than that of the reproductive, their transference is highly unlikely in detectable quantities. You see, THC is metabolized mainly in the liver. It is detected through hair, urine, blood, “oral fluid” and sweat. There seems to be no evidence of it being found in genital fluids.
Another researcher, who wishes to remain anonymous, brought up the additional argument against THC being transferred through sperm with the following, “Semen, as a vehicle for genetic material, would have no evolutionary advantage in bringing along extraneous chemicals like THC in the ejaculate. All that’s needed are the proteins, enzymes, fats, and DNA that would ultimately lead to the sperm’s survival and successful fertilization. Sperms have a job to do, they can’t be distracted by being stoned!” Moreno added, “If they could test for Marijuana use through semen, drug testing would be a lot more fun.”
