Myth #7 – All weed stays in your system the same amount of time.
Urine tests measure THC, and different strains of weed have different amounts of THC. The reg from that fourth-year community college student leaves your system quicker than the Omega Ultra Kush from a Colorado dispensary. If you’re stuck with the former, thank your neighborhood dealer for his/her continued dedication to crap weed, which will help you more efficiently pass a drug test. If you have the latter, thank them for keeping you space-level high, but curse the THC levels required to do so.
