Vice President Joe Biden's decision not to run for president in 2016 is a big win for cannabis advocates, according to Eddie Miller, the CEO of Green Rush - an organization that helps connect patients with medicinal cannabis dispensaries in the U.S.

"If Biden had been elected President, he would most likely have increased enforcement of Federal Anti-Cannabis Laws," Miller told Forbes. "The industry will undoubtedly support Clinton, who took a very neutral stance and Bernie Sanders who seems to be the 'Cannabis Candidate.' The industry has also donated to Rand Paul, a libertarian Republican."

Critics of the vice president have dubbed him an " anti-marijuana zealot" and credit him with crafting the legislation behind America's "War on Drugs" and mandatory minimum sentences for cannabis-related offences.

So they will surely bid him good riddance.
