You mean like selling or possessing alcohol?
Our drug laws aren't laws. I learned that from watching how we enforce them. They earn money for the states and counties through asset seizures, but they don't apply to people with money or influence.
Our drug laws aren't laws, they're just price supports for the worst kind of thugs and gangsters. Cocaine, methamphetamines, and heroin are cheap without price supports. Gangs didn't fight turf wars over the right to sell weed (and they still don't because even with the state propping up the price, the sales price doesnt justify the cost of violence). Budweiser doesn't send hitmen to whack the guys driving the Miller distribution trucks.
The animals that run the cartels murder people for sport and occasionally sacrifice human beings on the off chance that it might bring their drug mules good fortune. They write warnings to the public on the sidewalks with the organs of their victims. Their version of a hit is to massacre a whole restaurant with a machine gun armed suicide squad. They aren't a squeamish or anxious crowd.
You know what they fear? That one day, we might wise up and end the price supports that are making them rich and powerful. You dont realize it, but you are the single most important person that the cartels employ, and the best part is that your lack of understanding means that you're willing to work for free.
The law exists because we as a people choose to uphold it. Not the cops, not the courts, but the people. Laws that we refuse to enforce weaken all of the other laws.
