In his initial campaign announcement on his blog, he originally said he would run a write-in campaign either with the USMJP or as an independent:
So, wait…am I declaring myself a candidate for President of the United States in 2016? Yes, yes I am. I am going to launch a campaign as a write-in candidate, either independently or with the backing of the United States Marijuana Party. I do not have a nine-digit war chest, nor do I expect to raise nine-digits worth of war cash, so to be completely honest, I know I’m playing for fourth or fifth place in the final windup. I do, however, intend to chronicle this experience over the next twenty three months or so for an eBook release, both date and title obviously to be announced later on.
However, he now claims to have already attained ballot access in 10 states. I can find no independent verification of this claim. IPR did report previously that the Marijuana Party (possibly USMJP) is petitioning for party status in Nebraska.
The U.S. Marijuana Party was founded in 2002 by Loretta Nall. The party advocates for a number of socially libertarian positions, chiefly the legalization of cannabis. The party has never previously nominated its own presidential candidate, but did endorse Libertarian Gary Johnson in 2012.
