I think that as long as drugs are scarce and expensive, people will be more into it. If the are abundant and available, people will treat it as other vicious products like alcohol, cigarettes. But if they do that they won't be a business as they are right now. About a century ago alcohol was illegal and the black market of it was violent. People need access to health, education, food, once the basics are covered the need for finding a relief with drugs will go away. But that society is far away to be true yet. We need to awake.
