Please let me enlighten you.
If herb was legal (like it is in Europe say) and Americans had the freedom of life, liberty and pursuit of happiness, to grow herb in their own gardens, to smoke in their own homes if they wanted, the cartels would exist nor would these problems refered to in your article.
So next time your enjoying the freedom of drinking a beer or buying a round, just think about how there are tens of millions of Americans who would like the same freedom to light up a spliff next too and be treated as a fellow human being and relax in the same way. Our freedom of drinking was once illegal remember. Until that time that herb does become legal, people that enjoy the herb will keep with the American tradition of fighting for our freedom and be willing to take costs of doing so.
So if your pissed you should not be so prude and partake. You just might feel happy and be wise.
