Do flush free Niacin cleans the drugs up in you?

Different drugs stays for different amount of time and for different reasons. If you are trying to pass a drug test, don't trust a vitamin, go to a health food store and talk to the sales clerk and tell them what you need to be clean of, they have money back guaranteed stuff, it's expensive but it works. Pot is going to stick around the longest as it imbeds in the fat cells and it will stay for 4 to 6 weeks. Tranquilizers will stay for a week, most other stuff, just 3 days. If you are trying to detox, the health food store has stuff too.
