Where in the article did it argue for or against drugs? It is more of a sociolgical reading, discussing patterns of drug use among Americans across generations, rather than an activist paper calling for legalization, or a populist one calling for stricter control. Anthropologists have studied and documented all manners of "unacceptable" human behaviour in primitive/savage societies, including cannibalism, incest, and pedophilia among others, but that doesn't mean they're passing judgment on their subject culture. I think we can extend a similar academic courtesy to the greatest and most savage of all societies :-)
