Those links of yours deal wtih cannabis isolates and active compounds, though, Storm Crow. Not whole smoked cannabis. That's what makes those abstracts and summary links so dangerous here, if you ask me, because so many blind cannabis optimists want to misinterpret and conclude that it means the same thing for smoked cannabis or for humans. A huge percentage of that research has been done on lab mice. So the neuroprotective effects of CBD or THC in mice doesn't by any means mean the same protective effects are true about whole, smoked cannabis for humans. Not by a long stretch.
