I suffer from mental illness, I was at one point in time sitting with 6 different psychotropic drugs, turning me into a complete zombie.  Since committing to microdosing with the plant I've been weaned off every single "so called medicine".  My mood has never been more stable, I can actually concentrate again at work (I'm an accountant by the way), my wife has her husband back, my boy has his dad back and I recently became a partner in the practice I work for...  So it most definitely didn't cause my mental problems, it's solving them.  I am by no stretch of the imagination considered lazy and I don't think my intelligence is going down the toilet. Cannabis seems to be neuroprotective and even promotes neurogenesis (there are studies that elude to this, it's not wishful thinking).  The biggest problem is people don't understand the plant.  Please research:  The Endo-Cannabinoid system in humans, micro dosing with cannabis and the different effects of indica vs sativa dominant strains.
