Writing in 1925 regarding a proposed ban on interstate commerce of revolvers:

“The real victim of moral legislation is always the honest, law-abiding, well-meaning citizen—what the late William Graham Summer called the Forgotten Man. Prohibition makes it impossible for him to take a harmless drink, cheaply and in a decent manner. In the same way the Harrison Act puts heavy burdens upon the physician who has need of prescribing narcotic drugs for a patient, honestly and for good ends. But the drunkard still gets all the alcohol that he can hold, and the drug addict is still full of morphine and cocaine. By precisely the same route the Nation’s new law would deprive the reputable citizen of the arms he needs for protection, and hand them over to the rogues that he needs protection against.

Ten or fifteen years ago there was an epidemic of suicide by bichloride of mercury tablets. At once the uplifters proposed laws forbidding their sale, and such laws are now in force in many States, including New York. The consequences are classical. A New Yorker, desiring to lay in an antiseptic for household use, is deprived of the cheapest, most convenient and most effective. And the suicide rate in New York, as elsewhere, is still steadily rising.”
– H. L. Mencken, “The Uplifters Try It Again”

As it was then, it is now, and always will be. Prohibition (of booze, drugs, or arms) hurts only the law abiding.
