My brother got an important job and he will be drug tested in approximately 4 weeks. Weed is legal here in Washington and for much of the past several months he has smoked about once a day. However it is a disqualifier for this job. What methods would you use to get as much out of his system in the meantime as possible? And what to do the day of the test? It is stored in fat cells and I was thinking liver optimization for several weeks and then maybe suppression of FFA liberation the day of? Any other ideas?
