Go to Symptoms & Conditions Buy the Book on AmazonThis comprehensive sourcebook combines evidence-based insights from more than 1,000 studies from cannabinoid and consciousness research to present a convincing case for the powerful healing effects of medical marijuana on over 100 chronic symptoms and diseases. Written by a former paramedic with a PhD in alternative healthcare, this in-depth reference shows that the subtle shifts in awareness commonly observed in cannabis-using patients vastly contribute to these compounds' therapeutic potential.
The rating for each medical condition is based on the average qualitative therapeutic value of cannabis as a treatment sourced from the results of clinical studies for that particular medical condition.
The rating points are on a scale of zero to five with zero indicating no observed therapuetic value and five indicating significant and demonstrably scientific therapuetic value. It is the total value points of each study divided by the number of studies conducted for that condition.
More information about each rating and condition can be found in the Cannabis Health Index.
