Maximum of us are keen to know that how long medical cannabis stays in their system in order to pass a drug test.THC, or delta-9 tetrahydrocannabinol is the primary(main) chemical compound in the marijuana plant which is entirely responsible for the euphoric high experience indeed.After the inhalation process THC entered in to the bloodstream right away via lungs. THC is the active ingredient in marijuana and the chemical responsible for the high. However, urine tests detect a different chemical called THC-COOH.The cannabinoids are fat-soluble and are stored in body fat and released from there over time, so whether they show up on drug testing depends on many factors, including how much cannabis has been used over what period of time, how much body fat someone has, exercise patterns, diet and others. However if you are interest enough then you may visit Mjwellness in order to know this fact in detail. Hope it will be helpful.
