Alcohol is much more deadly.
Medical marijuana used to be a way for recreational activities sers to get around the laws, but now that it is being legalized it has a lot of real promise for medicine.
Marijuana + genetic modification = super drugs in the near future.

I remember sitting in a car in a parking lot in Denver while a friend who legitmately qualified for medical pot (PTSD and back pain) was getting a prescription. While I waited, all kinds of able-bodied young men walked into the dispensary. Finally, an older man with a cane got out of his car ... and went the florist. Pretty funny. At least Colorado ditched the pretenses.
