interesting article. Though Im always sceptical of marijuana studies since they all contradict each other, this one seems to be testing something that hasnt been tested before. But regardless what any studies show I know from experience that pot can be a catalyst for shizophrenia. Ive only stopped smoking for four months now and luckily the effects do seem to be going away. One reason I had no problems with smoking in the past is that there is lots of evidence that all effects of cannibus go away within a year, which I do believe ,from seeing people who have quit. But saying that, you do actually have to stop for the negative effects to go. I wonder if the problem wouldnt be much less if all the weed wasnt so potent like its become.
