I was a musician for years (70s/80s/some 90s) giging mostly across Canada so long drives and lots of cannabis smoked. I would rather be with a driver who smoked pot then drank. No cannabis can not cure cancer but it does help ease the adverse symptoms of treatments for cancer. CBD basically fixed my loss of Cartlidge in my knees but it takes a long time to work. And even my dentist approves of me using it to reduce inflammation after dental visits. SO CBD and THC for a hangover works very well. There are many more compounds in cannabis that the medical/scientific community are finding. https://bluebirdbotanicals.com/blogs/understanding-cbd/meet-your-cannabionoids
