Show me proof that your lady lived that long because she smoke joints.
maybe you can derive such proof from the obvious evidence of cannabis and it's endless medicinal effects... such as anti-cancer, regulation of bone growth, regulation of many of our regular body functions, as well as brain cell protection and growth, antioxidant effects on all cells as THC, many other cannabinoids, as far as I know many terpenoids and flavanoids have been found to have an antioxidant effect.
they say we all have a cannabinoid deficiency from bad diet or whatever, and by smoking/ingesting cannabis daily we cure this deficiency... so yeah, I'm not gonna pull up hundreds of articles because they are pretty obviously there, NORML.org has a nice summary of some of the more obvious medicinal effects... if you dig deeper you can find the shit I already talked about.
but honestly I'm not one to cite my sources 100%, I may do it 25% of the time, but the rest of the time I really don't care to prove myself to people who are far too doubtful for their own good. if you took what I said with a somewhat open mind and did a little bit of research yourself instead of attacking my knowledge, you might actually LEARN something.
but it's all good, I'm just gonna ignore you all now. I've said all I can.
