There are probably many/a combination of reasons. One thing I think that hasn't been brought up in this thread yet is a smaller amount of popular media portraying marijuana use in a tolerable light. In terms of movies, how few and far between are big weed movies? Was the last one Pineapple Express, 15 years ago? Go back a few decades and there were a bunch of big movies, songs, etc. year after year about smoking weed.
