Fear seems to be the biggest factor against making drugs legal. This logic is part of the problem. We can't look at the world as a group of idiots not to be trusted to take care of themselves. Our prison system will benefit as well due to a smaller population of inmates. Drugs are dangerous, whether they are legal or illegal.
Drugs are available regardless of what our government does.
Today, drugs are available to anyone determined to get them. Numerous lives are put at risk trying to stop this availability.
