Peter Lewis is an advocate of taxing and regulating the use and sale of marijuana and is one of the main financial backers of the recent, partially successful, campaign to legalize the use of marijuana for medical use in the U.S.
In January 2000, Mr. Lewis was arrested and charged in New Zealand for possession of marijuana. Lewis pleaded guilty to three charges and paid a substantial fine, though under New Zealand law he was not required to serve time in jail or prison. According to his lawyer, Marie Dyhrberg, Lewis used the marijuana on the advice of his doctor for pain relief after the partial amputation of his leg in 1998. He donated $3,000,000 to Marijuana Policy Project in 2007.
