Can frequent cannabis use in adolescence cause any real objective damage to the mind permanently, and how would I know?

It’s difficult to explain what it feels like as a cannabis patient to hear doctors talk about people dropping dead from overdosing on that new stronger cannabis!
Nor how it feels to have your medicine constantly listed as if it were a bad thing, a substance of abuse (not addiction, more ignorance, it doesn’t stimulate that part of the brain’s reward centre) instead of the life saving panacea of medicine that you can grow in your own backyard….think about it!
Thanks to NORML for compiling this research!
Cannabinoids & Neurogenesis
“Study turns pot wisdom on its head,” pronounced the Globe and Mail in October. News wires throughout North America and the world touted  similar headlines — all of which were met with a monumental silence  from federal officials and law enforcement. Why all the fuss?  Researchers at the University of Saskatchewan in Saskatoon found that  the administration of synthetic cannabinoids in rats stimulated the  proliferation of newborn neurons (nerve cells) in the hippocampus region  of the brain and significantly reduced measures of anxiety and  depression-like behavior. The results shocked researchers — who noted  that almost all other so-called “drugs of abuse,” including alcohol and  tobacco, decrease neurogenesis in adults — and left the “pot kills  brain cells” crowd with a platter of long-overdue egg on their faces.
While it would be premature to extrapolate the study’s findings to  humans, at a minimum, the data reinforce the notion that cannabinoids  are unusually non-toxic to the brain and that even long-term use of  marijuana likely represents little risk to brain function. The findings  also offer further evidence that cannabinoids can play a role in the  alleviation of depression and anxiety, and that cannabis-based medicines  may one day offer a safer alternative to conventional anti-depressant  pharmaceuticals such as Paxil and Prozac.

Not only has modern science refuted the notion that marijuana is  neurotoxic, recent scientific discoveries have indicated that  cannabinoids are, in fact, neuroprotective, particularly against  alcohol-induced brain damage. In a recent preclinical study — the irony  of which is obvious to anyone who reads it — researchers at the US  National Institutes of Mental Health (NIMH) reported that the  administration of the non-psychoactive cannabinoid cannabidiol (CBD)  reduced ethanol-induced cell death in the brain by up to 60 percent.  “This study provides the first demonstration of CBD as an in vivo neuroprotectant … in preventing binge ethanol-induced brain injury,” the study’s authors wrote in the May 2005 issue of the Journal of Pharmacology and Experimental Therapeutics.  Alcohol poisoning is linked to hundreds of preventable deaths each year  in the United States, according to the Centers for Disease Control,  while cannabis cannot cause death by overdose.
Of course, many US neurologists have known about cannabis’  neuroprotective prowess for years. NIMH scientists in 1998 first touted  the ability of natural cannabinoids to stave off the brain-damaging  effects of stroke and acute head trauma. Similar findings were then  replicated by investigators in the Netherlands and Italy and, most  recently, by a Japanese research in 2005. However, attempts to measure  the potential neuroprotective effects of synthetic cannabinoid-derived  medications in humans have so far been inconclusive.

Cannabis is good for the brain, and good for the body.
Thanks for asking!
