Yeah, I guess I could have been more specific. As a previous post said, pot isn't really considered a "drug" here. The Club's rules are stated pretty clearly, but I think they just hope for members to arrive somewhat lucid, and understandably don't allow using on premises of the facility that they rent for their events.
As they also state in the Conduct Rules: "The club may, from time to time, host non-sexual social events at which alcohol may be available, and events hosted privately by individual club members may or may not include alcohol, but all JO events hosted by Rain City Jacks are designated alcohol and drug-free."... So, they aren't prudes about alcohol and pot, but they have to be concerned with possible injuries, insurance issues, and maintaining a good relationship with the building's owners, just like the bath houses do.
