Recreational marijuana use has now been legal in California for six months and counting. On the surface, you’d never know that anything has changed. Since the passing of Prop. 64 in November, there have not been red-eyed, burnout bohemians strewn across the lawns of Griffith Park, nor masses of wasted youth in irreversible states of hysteria. Instead, on a hot Saturday afternoon in May, a group of lithe twenty-somethings clad in the kind of spandex that doesn’t leave much room for snacking gathered on a rooftop in the shadow of the Hollywood hills to practice yoga, and get high.

“Let’s all take a puff,” said Equinox yoga instructor Derek Beres to the students at the beginning of class. In unison, they inhaled from vape pens by Bloom Farms, a San Francisco–based medical marijuana company that also sells pre-rolled joints, and settled into mountain pose.

Those who chose to opt out of vaping THC could enjoy the anxiety-quelling benefits of CBD—the non-psychoactive compound in the cannabis plant that has been found to reduce epileptic seizures—baked into “cookies” made of clusters of organic seeds sweetened with dried fruit and cinnamon for the occasion.

After bites or drags of hybrid oil, students calmly and intently moved through warriors one and two, downward dogs, and pigeon poses to the sounds of ambient reggae. The hour-long class was short, and the breeze nice. Over post-savasana, CBD-infused cocktails, relaxed attendees traded protein tips and made plans for their next group hikes.

In the media, stoners have never held a strong reputation as fitness buffs, but leave it to the kale-juice swilling, kettlebell-swinging wellness worshipers of the West to change that. Medicated yoga classes, retreats, and athletic events like the 420 Games are popping up all over the coast, as well as in Colorado and Washington, D.C. Earlier this year, San Francisco opened its first “cannabis gym,” Power Plant Fitness, which encourages members to get high while raising their heart rates. So why the sudden marriage of fitness and weed? “It’s been happening for a long time,” says the Bloom Farms founder and former Wall Street trader Mike Ray. “Yoga and cannabis have gone together for as long as yoga and cannabis have been around.” It’s true; many believers quote the Vedas when saying the joyful “herb” in sacred Hindu texts and yoga sutras is actually cannabis.
