For those who don’t know what Proposition 19 (or “Prop 19″) is….it will make marijuana legal for adults over the age of 21 in California. Among Buchheit….Facebook co-founder Dustin Moskovitz, Napster founder Sean Parker, Paypal Co-founder Peter Thiel and retired software mogul Steve Silberstein have all made donations in support of the proposition, which will be voted on tomorrow (Nov 2). According to Buchheit, legalizing marijuana will create a more safe and sane drug policy.
