As a person who has used pretty much daily since 1966 and who knows many others who have done the same it has not been my experience that people are having ANY healthy issues due to the use of cannabis. I spend my summers with a bunch of ancient musicians. We drink alcohol, smoke pot and play music most if not all are in good health and mentally capable. We are all in our 70s and 80s. Every year we lose someone but we have not been blaming cannabis for people dying in their 80s.
