I agree. It's going to get complicated though. There are hundreds of cannabinoids we're aware of with barely any scientific understanding of the effects. CBD, CBN, and CBG all started popping up in dispensaries in different combinations with THC. We still don't really fully understand what they do. There are also more potent versions of THC like THC-O (1)
