Something SAFE.... And you use vodka and whiskey as an example of that?! Gosh that is annoying.... That surely was a sarcastic comment right? If you actually think that marijuana provokes more criminal activity than alcohol, you're crazy. Or drunk. Lol... 

Here's the thing people, the problem is with these INDIVIDUALS that commit the crimes. Who obviously don't have good morals, or self-control, or they're just flat out greedy people... Add ANY drug (or money) to that personality type and it will not end well. 

It's pretty stupid because many drugs can be great for medicinal use, but instead it's abused. Human nature. It's not always beautiful.
