Okay, sure... but there was a helluva lot of scaremongering going on in Anslinger's day, and he was a big source of it. Look him up. He had to have something for him and his post-Prohibition crew to do so bad, he got a lot of gullible people to buy the "Reefer Madness" line. Better he should've gone after cocaine or heroin, as today.
Here's some of Anslinger's scaremongering examples:

I know you won't like the sources, but there they are, and that's what the man and other people like him said back then.
