Ever since I was a kid I use to watch old black & white movies. There were some old movies that caught my attention. These were of back in the old days around New York city where most men & women always wore well dressed clothing (Ex: men wore tuxedos/business suits, while women always worse dresses that were long, yet they all wore fedoras while very few women did not.)
Aside of this there usually were parts in those movies where the bad guys would capture random victims, by use of some kind of either a cloth/handkerchief that was soaked in some kind of chemical, where the bad guy would cover the cloth/handkerchief over the victims nose & mouth, which would quickly put the victim to sleep.
I thought twas all a hoax, yet I eventually learned whatever those chemicals are were not really used on the victims during the movies, but the stuff literally exists. What I want to know is... What are the chemicals that were used on those cloths/handkerchiefs that had cause the victims to fall asleep so suddenly?
