Marijuana Was First Prohibited For Neither Of These Reasons
This was definitely not prohibited because of racism, and corporate corruption doesn't always have to do with drugs. It was/is mainly a issue of danger because of the way people go about obtaining it, and control. The government cannot control it because it is wide spread in almost every country. If they cannot tax it, they lose money and it can hurt the economy. This isn't corruption though, because in a way it is not out of the control of government and nobody is abusing the power of this illegal drug in politics.
