Be careful what you read regarding round-up, funding behind the studies is easy to hide. The industry likes tout their results from the active ingredient only and not the remaining additives that combine to do greater harm. I've seen this information out there but you typically have to go outside of the US to find it.

Good to hear we are working toward that area and it sounds like there are a ton of variable to take into consideration.

Here's the patent I posted in a reply above:

""The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and HIV dementia. "

That's the main problem I see, the research funding comes from corporate and government interests with hidden agenda, IMHO. Hmmm... there has to be a blockchain solution for this.... right? This is more in my area :)
