I agree with most of what you have shared @thechurch and can add that:
CBD is not physchoactive and that CBN develops when hydrogen oxidizes from THCA over time. CBN is what produces a really good, deep sleep and works synergistically with THC, once both are decarbed from their raw form. I think this is one of the biggest benefits that cannabis offers...it lets people get into and stay in low sleep state longer. This lets the body heal and repair itself. So whether that's from illness or work-out strain, repair will happen efficiently if people can achieve good quality sleep. :)
