Richard Nixon—derogatorily nicknamed Tricky Dick for his dirty campaign tactics as a senatorial candidate—served as U.S. President from 1969 to 1974 when a scandal forced him to resign. Under his administration, the government declared war on drugs (June 17, 1971), solidified cannabis prohibition in the Controlled Substances Act and amped up enforcement by establishing the Drug Enforcement Administration (DEA). Even compared to the Reagan Administration, Nixon is considered the Supreme Leader of the Drug War championing cannabis prohibition based on political and racist motivations. He even tried to deport former Beatle legend John Lennon due to a cannabis possession arrest years earlier in England. When it comes to presidential prohibitionists, Nixon truly is the biggest Dick of all.
