According to my home THC test strips; it takes from 15 to 30 days. That's going from the faintest line to a faint line...on the test strips.
Dutch Pimp Reviewed by Dutch Pimp on . How long did it take you to clean out naturally I hear all these stories about individuals using substitution or dilution, but I am curious to know how long it took people to clean their system naturally. I know for me I didn't test negative until day 60, and I used my first morning urine after working out the day before. So clearly the 30 days is not applicable to chronic everyday smokers like myself. Let me hear your stories. Rating: 5
