You are absolutely right, and perhaps the most under reported effect of the war on any vice is that vice enforcement becomes just as lucrative. It's easier to bust someone for possession than reckless driving, assault, you know, things that have to be verified at the time of offense. It's not that the police, prosecutors, prison owners or lawmakers are bad people, they just deal with corrosive incentives. Just like drugs, drug crime enforcement is a cheap high that gets you to places you wouldn't likely be if you played by the boring rules.
