Hi Bonbon...
I had to go look it up! A "sherm" is a cigarette that has been dipped in embalming fluid. I suppose that could include any type of cigarette, including marijuana. Back in the days of yore, I had a friend who bought some pot that had been dipped in embalming fluid. It made him terribly ill. In this particular instance it was a scam... the dealer had dipped the pot to give it a better color so he could sell it at a higher price. You'd think it would have raised suspiscions that it was blood red. I'm gonna go read some more.
RUN!
