William O. Douglas,
Minor v. United States — Dissent
“ Petitioner did, of course, have the option not to sell the heroin, and in that sense his compliance with the statute was indeed quite possible. This argument, however, overlooks the fact that the statute does not simply outlaw all sales of heroin. The critical interest of the Government is necessarily in the collecting of the tax imposed by the Act, and it is the order form which provides the crucial link to this proper constitutional purpose. ”
