Gary Johnson explains why he won’t smoke weed as president — and why he gave it up on the trail

Johnson, the former CEO of Cannabis Sativa Inc., which sells medical-cannabis products, said he stopped smoking marijuana once he began campaigning.

If elected, he said he’d put the habit on hold because he believes that he’d have to “be the best that you can be” when serving as commander in chief.

The former two-term governor of New Mexico, who made a bid for the presidency as the Libertarian candidate in 2012, is polling at 8.5% against Donald Trump and Hillary Clinton, the presumptive Republican and Democratic nominees, in the RealClearPolitics average of several polls. In a recent Fox News poll, Johnson garnered as high as 12% of the vote in a three-way race.

If Johnson can break 15% in enough polls ahead of the fall, he can make his way onto the stage in the general-election debates.

He wants to be on his A-game in the Oval Office.

Gary Johnson: ‘I’ve stopped using marijuana’ during White House bid

During an interview with USA Today, Johnson was asked how long it’s been since he’s taken the drug.

“It’s been about seven weeks,” he responded, adding that he would not partake in the drug during his term if he’s elected. “I want to be completely on top of my game, all cylinders.”

Johnson has long advocated for legalizing the drug, saying on Thursday that there is “an unbelievable disconnect” between politicians and the public on the issue.

“I haven’t had a drink of alcohol in 29 years because of rock climbing and the notion of being the best that you can be, and in that same vein I’ve stopped using marijuana of any kind,” he said earlier in the interview.

"I want to be completely on top of my game, all cylinders," the Libertarian says.
