Remember the stories, during prohibition, of how the criminals organized, made money, bought off politicians, bought off police, and formed a huge organization that made, distributed, and sold liquor? Well, just substitute marijuana for liquor today, and the same story continues, only much worse.
Just look at all the money that is wasted in the frustrating and impossible job of stopping marijuana (and probably the harder drugs too) - airplane reconnaisance to identify fields of marijuana, police who arrest the users and sellers, jails that are crowded with marijuana users and sellers, border police and patrols who search for marijuana imports - on the ground, in the air, and on the seas. What a waste. Without noticeable success. There is just too much money involved. Even the most honest of the law enforcement officers have to be tempted, once in a while, to look the other way.
Suppose that marijuana were legalized - just look at the productive jobs that would be created: pharmaceutical houses could manufacture and package marijuana that was free from poisons and safe to use. All those jobs would employ people who would pay taxes. And think of the tax revenue from the legal and legitimate sale of marijuana to the city, county, state, and federal governments. I don't want to rub anybody the wrong way but, I hope the lobbyists for the mobsters who would see a large portion of their profits dwindle, don't pressure the Congress not to enact such legalizing legislation.
Talk about job creation. Here's an easy way.
