Yeah, but many people don't actually think War on Drugs policies are a model for civil liberties that should be extended beyond that domain (or, in many cases, even tolerated in that domain.) That policy has been effective, I guess, in promoting the sales of alternative “decongestants” (that don't actually work), though it did little to curb use and harms from the drugs it was supposed to control by attacking supply.
