Destroying one’s own self has no victims, any more than bodybuilding does. If we should be free to build ourselves, we should be free to destroy ourselves.

If you've known anyone addicted to the list of things you mention, you should know that at some point, they are no longer "free to destroy themselves". They are continuing to destroy themselves out of a chemical or phycological necessity. The people who deal drugs or own casinos are running predatory businesses and it should be illegal, just like other predatory business practices are.
