I'm not innocent. I'm a human being. I've offended people and made an ass of myself and done things that I regretted. Does that make me somebody worthy of death? (Frankly, if I were to make a list of "things that would be good excuses for somebody else to kill me," drug use wouldn't be in the top 10, because at least that hurt nobody.)
What about cool, athletic Juan in Mexico who was executed for refusing to join the Zetas? What about mayor Carillo who was gunned down in an intimidation assassination?
That's a good reason to encourage legalization followed by business supervision. Used to be people were killed over alcohol. Now people have turned winemaking into an art, and not many alcohol gang deaths occur.
What about Jake who died of an overdose in the frat house because he thought drugs were cool?
What about my grandmother, who died of lung cancer? Or the people who die of alcohol abuse?
The solution is education. My college has many hard drug users, and zero hard drug deaths.
