Study: Exercise increases marijuana user’s THC levels

In Top Stories by David Silverberg

A new study, published in Drug and Alcohol Dependence, found that levels of THC were higher by an average of 15 percent immediately after marijuana users exercised.

The study authors conclude: “These results suggest that exercise may elevate blood THC levels by releasing dormant THC from fat stores.”

While THC levels were boosted in these exercisers, researchers didn’t study if intoxication increased after working out, but said they plan to carry out more tests to test that conclusion.

Time writes “other research found that even in people who do not smoke marijuana, both exercise and stress can increase activity of the brain’s natural cannabinoid system and lead to the release of the body’s THC equivalents. Those agents contribute to ‘runner’s high’ and other pleasant, dreamy feelings during workouts or stressful experiences.”
