The logic of legalizing marijuana is solid. It does not lead to 'hard' drugs, it is not as addictive as tobacco or booze and it provides help to many who need it. A more effective and safer way to calm people than pills.

So what's the problem? Legalizing pot and controlling its production and distribution threatens too many:

Politicians who risk losing the support by supporting unjustifiably strong laws and punishment to curry vote and contributions.
Police who will lose much of their arrest records.
Prison officials and guards who will see their population drop.
The Drug Enforcement Agency.
The criminals who control the marijuana production and distribution such as the Mexican Drug Cartels. They may be counted upon for large donations to politicians who sensationalize the issue.

The list goes on and on. Marijuana is the largest cash crop in many states. While I support Congressmen Paul and Frank and will write to my Congressman to support it, I see no chance that it will go anywhere.
