The Nevada Athletic Commission has been notoriously hard on fighters testing positive for marijuana in the past, but it could be changing that stance in the near future.According to the agenda for the upcoming NAC hearing on Friday, the commission is going to discuss “the possible exclusion of cannabinoids from the list of Prohibited Substances and Methods.” TMZ Sports first reported the news on Tuesday.According to the report, the odds are favorable that the NAC will amend the rule to remove marijuana as a banned substance. However, even if the change passes, it will be a minimum of three months before it can take effect.Fighters testing positive for marijuana in Nevada have received some harsh sanctions in the past. Most notably, Nick Diaz was initially suspended five years and fined $165,000 after testing positive for marijuana following his bout with Anderson Silva at UFC 183 in Las Vegas. Diaz would later reach a settlement with the NAC reducing his suspension to 18 months and fine to $100,000.
