                                                           Negative - Anxiety, Paranoia, Social Dysfunction,   Memory Loss, Losing your sense of self. Positives - Relaxing, harmless compared to smoking/drinking, mind expanding, self-developing, food tastes amazing and most things are funny. Consistent heavy long term use however will decrease the positives and accentuate the negatives. Source: My life.
