Control can be through prohibition or supply. The total or even partial prohibition of drugs gives the government considerable leverage for other types of control. An example would be the selective application of drug laws permitting immediate search, or “no knock” entry, against selected components of the population such as members of certain minority groups or political organizations. But a government could also supply drugs to help control a population [with] the governing element employing drugs selectively to manipulate the governed in various ways.171
