Robert Platshorn is an American hero, at least in my eyes. Robert Platshorn served more time in prison than any other person for a nonviolent marijuana offense (30 years). Since his release, Platshorn has turned his attention to activism - specifically extolling the virtues of pot to seniors through his Silver Tour. Every campaign in America should be hiring this guy to spread his message to the most vital demographic when it comes to reforming marijuana laws. HIGH TIMES caught up with Platshorn at the Seattle US Cannabis Cup.
