The NCAA raised its testing threshold for marijuana and recommended reduced penalties for positive tests on Friday in a significant change to its cannabis-testing approach. The new guidelines, which are in line with THC threshold levels established by the World Anti-Doping Agency, raise the threshold from 35 to 150 nanograms per millileter, the NCAA said.

The NCAA also recommended a new penalty structure for positive tests that allows athletes to remain eligible if the school offers "a management plan and education." The new structure must be adopted separately by each NCAA division as part of their bylaws.

The proposal:

First positive test: No loss of eligibility if the school provides a management plan and education for the student-athlete.
