Yes, until it's legalized at the federal level in the U.S.A. nobody is going to risk any time, data, money or research on anything meaningful regarding cannabis research and if they did, publishing it would be the end of that program. All information from there is anecdotal at best. Some is useful in a given set of circumstances with some people, but nothing really quantifiable. I'm not saying it doesn't work, just it's rather a lot of local stories, myths, wives tales, yarns and related impressions and experiences from everyday users. Legalized federally would open the doors for research and banking without the government interfering at the basic level without assets being seized.
