An excellent read. Not only are there huge legal barriers, but also social ones. The propaganda launched against cannabis in the last century has taken hold, and fellow scientists who aren’t interested in the topic still fall victim to it.
That reminds me - for anyone who hasn’t watched Reefer Madness, it’s both hilariously inaccurate and an good example of propaganda that led to this situation:
We showed it at the film club when I was in college and the audience was laughing through the whole movie at the antics of the “addicts” in the movie.
