Behaviors that have long been considered vices include excessive or habitual indulgence in gambling, certain sexual activities, and the use of psychoactive drugs such as nicotine, alcohol or opium. Even in a world without vice‐specific public policies, vice would still be subject to informal social controls. Most vices, including forms of gambling, prostitution, pornography, alcohol, tobacco, and other psychoactive drugs, have met with prohibitions at certain times and places, including contemporary times and places. What has become known as the “harm reduction” or “harm minimization” approach to illicit drugs typically focuses on reducing the harms per incident, while being rather unconcerned about overall prevalence or whether the harms are external or suffered by the vice participants themselves. It is commonplace to note that the Internet has changed everything, and this trope would apply to vice regulation, too.
