I think it has to do with normalization. And this takes time. My parents would both probably connect people taking psychedelics with the Hippies, partly because they don't know better, partly because this is the picture they got in their rural alpine village describing psychedelics. Weed is slowly getting more normal, so that jokes they used to make died out a while ago. When we watched my brothers run the Amsterdam marathon they would even push us to try some with them. Meanwhile 20 years ago my father would have unironically put weed on the same level as heroin. He did not know better. Things like LSD are probably just further down the road for them, so it is a mixture of general acceptance within society, education about the substance and the commercialization of it.
