I'm reminded of this Twitter exchange, in which Alan Kay graffiti'd YCombinator's "Make something people want" poster to say "Make something people
need" and Paul Graham retorted that "making something people need but don't want kills startups".

The point of business is to create a customer. For that to happen, there has to be someone out there who has voluntarily decided they want to use (and ideally pay for) your product. The same goes for political movements - to build a mass political movement, you need a critical mass of people who voluntarily decide that this cause is worth investing time and money into.
By definition, addiction means that your voluntary choices are going to serve the furtherance of your addiction. So there's no customer there, and no profit potential, unless you're a drug dealer. Social interventions like drug treatment clinics could perhaps work, relying on the desires of loved ones, but it's very hard to help someone else unless they make choices to help themselves. When your brain chemistry has been altered so all it wants is more of the drug, that's not a given.
It's a hard problem. Unfortunately history hasn't been kind to populations with mass drug abuse; when I think of countries with a societal drug problem [1][2] or even subpopulations within a larger nation with widespread drug abuse [3][4], the cultures involved all basically collapsed. For countries, the general pattern involved top-down reforms -> military defeats -> revolution -> conquest by another power. For subcultures within a larger nation, it's the total marginalization of the group in question, assimilation into the larger population of the remaining productive members, and then long-term decay and blight on the remnants of the subculture.
