Absolutely and stunningly agree with what you write. Don't even have much to add. Maybe this:
The Government stems from the society that it represents. As that society is becoming more and more superficial (thanks to some of the addictions you mention), the Government is becoming the same. Maybe a little slower, as most of them are older, but steadily. But that's maybe too long term.
More likely: The drug problems come from a point that benefits the system, and the rich and powerful. Preventing drug abuse has a lot to do with community, starting at the household, and then the first safety net (neighborhood, village...). But the communities are falling apart thanks to the rising individualism, which benefits the capitalist system through self-exploitation and consumerism.
