no, i think that is a cover. Think about the lumber, alcohol, tobacco, private jail, DEA, and the pharmacitical industry is affected. Where do some the richest people in the world come from (well not the DEA) or invest in. Cannabis prohibition is keeping 100 Elites billionares and giving them lots of power. These elites aren't the nicest of people and wouldn't reveal the truth about cannbis and its wonders for the sake for what is right. They have worked too hard to get there power so why would they let cannabis ruin it.
When we legalize cannabis, it will affect the umber, alcohol, tobacco, private jail, DEA, and the pharmacitical industries the most. Remember the union towards the end they talk about this. Taxing it is not really the problem, they taxed hemp growing in the 1800's. They can tax cannabis on an industrial scale, but they can't tax the family growing a few plants in the garden, but most of the money will be coming through the industrial scaled cannabis growing and selling. That can be taxed with a few laws.
