Former NM Gov. Gary Johnson told the conservative magazine The Weekly Standard that he used marijuana for medical purposes from 2005-2008, before his state had passed a medical marijuana law.

Johnson has long portrayed himself as someone who has used marijuana. "I don't drink. I don't smoke pot. But I have drank and I have smoked pot," is a line we've personally heard the governor use in stump speeches at the NORML National Conference in Portland, the Seattle Hempfest, and the Cypress Hill Smokeout in San Bernardino, just three of the many pro-marijuana events Johnson has attended in support of his "Our America Initiative". The Standard interviewed the possible candidate for the Republican nomination for president and became the first journalists to press Johnson on the time frame of his past-tense marijuana references.
