Niacin can clean your system within 8 to 48 hours and a lot of water needs to be consumed after consuming it.
If I understand the effect correctly, it only masks the THC in your urinalysis test for a matter of hours after the intake of the niacin.
I knew a guy who completely flushed his system with lots of niacin and vinegar in about 3 hours one day after he last smoked.
Not too long, just a couple hours. But it is VERY uncomfortable.
No, niacin does not clean drugs - any drug - from your system. See the Related Question below for more information. Also, cocaine normally leaves your system in about 72 hours (3 days) anyway, except for heavy, long-term users, who may have to wait 5 days or even up to a week.
Niacin is no substitute for being clean. A Niacin purge is effective but you must start several days prior to the known testing time. Niacin purges the system quicker than without using it, and in most cases the body is clean in 72 hours, but chronic meth users should not bank on that time frame without using a Niacin purge several days in advance.
Niacin pills help the people who sell them make money, and I suppose they keep you from getting pellagra. They do pretty much bupkis with respect to "cleaning your system"; the only reliable way to do that is to stop using drugs and wait for the body to do so itself.
Niacin does not clean drugs -- any drug -- out of your system. It is entirely useless for that purpose. You might as well try cleaning your system with Pixie Sticks, fairy dust and moonbeams. Cocaine, including crack cocaine, is out of your system in approximately 72 hours (3 days) anyway, although it may take a week for extremely heavy, long-term users.
