Federal death penalty law: 18 USC § 3591(b)
"Despite drug trafficking being a federal capital offence in the USA, the country has never executed anyone for drug-related offences.250 Nevertheless, the USA remains the only country to have carried out executions in the Americas region in seven consecutive years.251 Donald Trump’s recent public support of the death penalty,252 his call for fast trials, and his support for Duterte’s bloody ‘war on drugs’ in the Philippines are very worrying,253 particularly as 2017 has seen some States, including Arkansas, Florida and Ohio, resume executions after long hiatuses.254"
