I'm sorry some smart person pointed out that I umed something wrong about the intent of drug laws?

Your question asks if drug dealers caused drugs to be made illegal or if drug users caused the illegality. The answer is both the users and the dealers caused it. Back in the 20th century when most drugs were outlawed, it was because of the effects the substances had on people were viewed to be harmful or addictive. I like what Chris Rock had to say about how "the white man" made alcohol legal while outlawing crack and pot even though alcohol caused much more addiction and disease than other drugs.
