The data matches the obvious. When Alcohol Prohibition ended, drinking related problems skyrocketed. If you outlaw tobacco, tobacco-related problems will plummet.
The question is whether you want to spend your resources stopping people from harming themselves. I smoked enough weed in college to know it impairs your driving and smoking anything is bad for you.
What is hurting Colorado is that people are still smoking black market dope. It’s legal to smoke it and it is cheaper than store dope.
CO is actually doing pretty well in the revenue dept, which probably explaqins Hickenpooper’s conversion from opponent to supporter. In 2017, they collected $247,368,473 from mj taxes on $1,507,702,219 in sales.
