I would argue that Marijuana has become why more potent over the years. My 70 year old Aunt was visiting CA from TX last year and she and my mother used to smoke a small bit of pot in the 80s. We visited a friend that has some (not my cup of tea) and she wanted to try it. She said it kicked her ass. That is antidotal, but it has been repeated over and over by various people over the years.
