And, if it were legalized, all of those things wouldn't be affected at all. Drug trafficking leads to violent crime. You know. Kinda like how Prohibition saw a rise in violent crime enough to cause Congress to sign a new amendment into place the rendered the Prohibition amendment null? In fact, Prohibition is actually an extremely fantastic example of how legalizing drugs would actually be more beneficial in the long run. During Prohibition, there was more drunkeness and more crime, two things Prohibition was supposed to curb. The same ideas apply with drugs.
