I agree, and just edited tose changes into my post. Thanks for pointing them out. The three studies I posted about in my last two posts, were the ones @biohacker mentioned in his second to last post. I noticed they were PubMed studies, which one of my doctors said is generally a good source for legitimate studies, so I checked them out first, and found some of this info to be pretty interesting. I'm going to be doing more reading of PubMed stuff, and sharing more of what I find to be important to this discussion.Thanks for those 3 studies @EverythingsHazy.
Study #1 is pretty objective and makes an effort to NOT overstate negative conclusions.
Study #2 is from the Am Journal of Addiction, a journal that will likely never publish anything except negative assessments of all cannabis use. 16 of the 48 subjects are in prison . One of this studies findings is that 100% of those in the study had "organic brain dysfunction in a test of visual memory immediate recall." This is OBVIOUSLY not a random sample of the general population and could never be used for predictive purposes or general applicable conclusions. The study sample population is quite extraordinary.
Study #3 contains the most objective and least pejorative attitude towards cannabis and I'm surprised you didn't highlight this conclusion because it's actually very good: "...a small medial temporal lobe is a vulnerability factor for substance dependence in general" and not the result of any amount of cannabis use. And this final one: "The lack of significant differences in GM volumes changes between young adult heavy cannabis users and healthy controls over time suggests that heavy cannabis use does not reduce regional GM volumes in this period. The cross-sectional negative correlations between medial temporal lobe volumes and the severity of cannabis use can either be a result of heavy cannabis use before early adulthood (with maximized damage before the onset of the current study) or represent a (genetic) vulnerability factor that was already present before the start of the study or even before the onset of the use of cannabis."
Also, I noticed the prisoner thing, too. That's hardly an accurate representation of the general public.
Something else I noticed in Study #2 was how they said the average daily use (in grams) for the subjects was "5.84.4 gr and 4.84.0 gr". Can anyone explain the second decimal point?
Also, I'm curious how the THC dose of vaporizing 1g of Cannabis compares to smoking 1g of the same Cannabis. I'm going to go look that up, but if anyone has an answer, feel free to share that info here. It could be useful to know how the two doses compare, when reading studies that focus on Cannabis smoking.
Long lasting effects of chronic heavy cannabis abuse.

Pubmed is great...I just input long term cannabis brain.
