Eric Wilson, a personal trainer and owner of Movement Sciences in Boston, can envision a time in the next three to five years when there will be different cannabis oils or strains designed to enhance specific activities.

“If you’re going fishing, maybe you want an indigo blend,” he says. “If you want to go for a long run, maybe a different one.”

In recent years, some advocates have called for professional sports leagues to allow marijuana use; former NBA commissioner David Stern said last year that medical marijuana should be removed from the league’s banned substances list.

The World Anti-Doping Agency, which provides oversight for athletic events ranging from the Olympics to the Boston Marathon, currently lists cannabinoids including marijuana as banned substances. And a spokesperson for the Boston Athletic Association said there are no plans to deviate from those rules.

Still, says McAlpine, “athletes for all of time have tried to find an edge to make them faster or stronger. And there will be people rushing to try this once they realize it’s not going to hurt them.”
