The joys of having dated a doctor.
To be blunt (no pun intended) most doctors don't know shit when it comes to THC and how to rid the body of it, I know, I am a PA for one. The only ones who know any factual information are the ones who have or still smoke themselves. Niacin does't do a thing in helping expedite the unloading of THC from your system. You are better off taking up smoking cigarettes if you want a sedentary boost to your metabolism but I am not suggesting anyone do that Exercise will trump any secondary metabolism boosting tricks tenfold so there is really no benefit in taking niacin if you aren't already taking it.
