If I smoke weed/dro today will the drugs be out of my system in two days? How many niacin should I take if so?
Ha sorry but theres is no way in hell to get drugs outta your system 100% in two days. But my advice to you would be get one of those drinks from the mark. they've worked for a FEW of my friends.
Niacin fails to pass a drug test over 90% of the time. Good luck but your S.O.L.
