If you live in one of the 26 states (or the District of Columbia) with legalized recreational or medical marijuana, you may partake in this substance occasionally or even use it regularly under a doctor's supervision. However, many employers continue to utilize pre-employment drug screens or random drug tests for employees who are injured at work or who demonstrate performance problems, and because THC (the active ingredient in marijuana) is fat-soluble, you may fail a drug test days or even weeks after your last use.
