Pharmacy/Marijuana/THC Metabolites


I am 170 lbs, exercise 2-4 times a week, and i drink 6-8 bottles of water a day. I was exposed to second hand smoke while riding in a car for an hour to an hour and a half. I continued on my daily routines and was drug tested 12-13 days afterward. How long will it be in my system for?

    There is no concrete data on marijuana second hand smoke.  I can only give you data that is available as if you were the person smoking the marijuana.  If you were the person smoking, random occasional use would be detectable in urine for approximately 1 to 6 days depending of liver and kidney function, body fate to store the marijuana and hydration.  Persons who smoke on a regular basis would test possible for 7 to 30 days depending on the same factors.  Hair testing shows all levels of use for approximately 90 days.

If you are unsure of the data please check
