I smoked last Wednesday night and took a drug test six days later. On Friday of the week that I smoked I passed a take home drug test. In total it was six days between the time I smoked and the time I had to take my pre employment drug test. Am I going to pass the drug screen? I am an infrequent user of marijuana. That was the first time I smoked in 2 months. Also I have 7% body fat.
