Stevens argued that it would be "profoundly unwise to create special rules for speech about drug and alcohol use", pointing to the historical examples of both opposition to the Vietnam War and resistance to Prohibition in the 1920s. Pointing to the current debate over medical marijuana, Stevens concluded, "Surely our national experience with alcohol should make us wary of dampening speech suggesting—however inarticulately—that it would be better to tax and regulate marijuana than to persevere in a futile effort to ban its use entirely."
