I've been a fan of Joe Rogan since NewsRadio. Glad he tried the pipe.
The study said very high content THC cannabis can possibly cause Schizotypal Personality Disorder in susceptible people who smoke large amounts, all day, every day, for extended periods of time. But the study was not definitive as there are other compounds present (more than 60) which could be the chemical culprits. This is completely different than saying cannabis causes schizophrenia. Personally, I suspect the high concentrations of cannabithiols are a main factor, alone or in concert, with the THC. :mrgreen:
