The 1930s featured an interest in Washington of controlling recreational drugs. Before the 1930s recreational drugs were only outlawed sporadically and by individual states. In the 1930s this changed almost overnight into a range of federal laws designed to universally criminalize the use of recreational drugs. One of the key figures in this change was Harry Anslinger, a federal administrator in charge of regulating narcotics. The Wikipedia article on Anslinger suggests that before the 1930s Anslinger had little or no concern over the recreational use of drugs such as marijuana/THC, and that he became a vociferous advocate of criminalizing marijuana only after the failure of the temperance movement, and this was a self-interested job justification action on his part.
Is this claim true, that the federal interest in controlling recreational drugs was largely a response to the failure of the temperance movement, or was there some other cause?
