Consider the punishment on conviction for drug dealers in this country, and the punishment on conviction for drug dealers in a couple far east countries - death by firing squad.
Legalizing a dangerous substance (and there is such a wide variety of potent drugs which cause havoc among humans) is a disastrous road to take. Just imagine methane, coke and crack cocaine available legally, and the awful danger to our young.
The drugs are mostly produced in other countries and smuggled into the USA. You want to tell me with our modern, advanced systems of detection and interdiction, and our tremendous weaponry, transport, and manpower, we cannot stop it all? Heck, yes, but for the little word called "corruption". Now that's where the real problem lies.
Anybody know what the penalty is for narco trafficking in Cuba?
