It's only been thirty-four years since Richard Nixon declared a war on drugs (becoming an institutionalized global war in 1973). Too early to call. We may need more decades and more prisons for the POWs.
At that time, the well-armed and medicated Elvis Presley was already an honorary Federal Agent-at-Large with the Bureau of Narcotics and Dangerous Drugs, and no doubt many pushers became nervous and went home to rethink their lives.
