drug testing filter: does niacin really clean out all the THC in your body? What is the effect of taking large doses of niacin?

I have a friend who has to take a drug test every month. He still regularly smokes pot, and beats his drug test every time.
His method is to take 5000mg of niacin for four nights in a row before taking the test. Niacin is a natural health supplement, which can be purchased at any vitamin store. The niacin bottle has a warning not to take more than 1000mg per day. When he takes the 5000mg of niacin, he gets the shakes, heavy sweating, and breaks out in hives. But, he beats the drug test everytime, so it seems to clean out his system.
Apparently, since niacin is a legal natural supplement, the drug test does not register it as a masking agent to beat the drug test.
Does anyone have any thoughts about this? It appears to work, but it seems strange to me. Also, what are the long term effects of taking 20,000mg of niacin in a four day period, every month?
