Salem to Salem: Sgt Pepper Pills

Billy Peddlarson and his Family refer to the hallucinogen pills over their radio as being "Sgt Pepper Pills". First of all, I know that LSD is a liquid and so, in real life, it would be pointless having these pills. They don't exist. However, for the purposes of the novel, there is a hallucinogenic pill and it does have the same effects as LSD, even stronger. I played fast and loose with science to come up with this. Alright, it's a Deus Ex Machina; it worked for the purposes I needed in the novel and so I used it a lot (in the book, I mean).
