Do drug dealers, politicians and law enforcement profit from the "War on Drugs"?

I mean, I understand it's the politicians fault for not revamping the system and ignoring what the people want. Look up any statistical poll and majority of Americans believe the Drug War is a complete failure. I blame money hungry politicians and people who are high up in the law enforcement community for keeping the status quo when are system needs to be revamped. How did the government ever get involved with trying to moderate human behavior and trying to enforce morality on people? I mean, you can't tell me locking up mive amounts of people have helped our country deal with a drug problem. Also, don't give me that same old rhetoric "well drugs destroys lives"...Well so do guns, cigarettes and alcohol. In fact, my closest family member has an extreme alcohol addiction and the last thing I would want is for her to be locked up for her addiction...and yet we continue to lock up people for choosing a different vice. Fact is, prohibiting anything never works, it just creates more violence, more addicts and more profits...Doesn't that mean the politicians, law enforcement and drug dealers are all on the same side in the end since they are the only ones who profit from the "War on Drugs"? I think it's pretty sickening if you ask me.
