Niacin

"You may have heard that too much niacin can be harmful because of

Internet rumors. The rumors falsely state that by taking a large amount

of niacin, people can flush the chemicals that show they've used

marijuana out of their bodies before they take a drug test. No studies

have shown that niacin can do this, and this can be very dangerous

because it may lead to niacin overdose.

Signs and symptoms of a niacin overdose include:

  • Rapid heartbeat
  • Skin flushing combined with dizziness
  • Itching
  • Nausea and vomiting
  • Abdominal pain
  • Diarrhea
  • Severe liver damage (hepatoxicity)

If you're concerned about a potential niacin overdose, talk to your

doctor to make sure you're taking the correct amount. If you think you

may have overdosed, seek medical attention immediately."http://www.mayoclinic.com/health/niacin-overdose/an01644

How big are the pills? The maximum recommended dose is 6000mg per day.

 
This is a bit late but you can block/reduce the side effects by taking aspirin about 30 minutes before the Niacin. A bit late now though.
 
what a fucking idiot, dude i took like 3 pills of 200mg and passes a drug test the next day, u dont need to kill your self taking that shit.
 
Fuckin funny. This kid I work with where we get tested somewhat regularly takes two pills right before he goes to bed. He's so used to it that he breaks out in rash and stuff while he's sleeping then wakes up with no effects. IT has to be so bad for the body, but it allows him to smoke pretty much whenever you want.
