So let me first say please don't tell me that using niacin pills to pass a drug test doesnt work because i know it does i have numerous friends that use it to pass drug tests all the time. my situation is im gonna be randomly drug tested several times a month for the next three months and i really dont wanna give up smoking for the next three months....i used the jello method on my first test and it worked but im not gonna have an hour notice for my next tests....can i just take one or two niacin pills a day and continue to smoke and pass drug tests with no notice? i know there is discomfort and i know the pills are expensive if i take them everyday but its all worth it for the mary
