WONDERING if DRUGS are used to render subjects highly suggestive to HYPNOSIS [as drugs have been a recurring theme on the show since the beginning, along with hypnosis]

Just saw a Charlie Chan movie "Black Magic" [from 1944] It involved seances, speaking to the dead, magician's tricks, Charlie Chan making jokes that's he's "psychic" -- and a master hypnotist/magician who turns out to be the killer

Backstory is: hypnotist found his wife was running away with his assistant -- so hypnotist faked his own death but really got plastic surgery to change his look, coming back to befriend his former wife and assistant -- then exacting revenge and killing them both

Hypnotist put a witness into a trance -- rendering her unable to speak [as she held an important clue] until Charlie snapped her out of it -- though she couldn't remember after that, and

Hypnotist put ex wife into a trance, making her jump off a building

Charlie Chan figures out that the secret to the hypnotist's success was that he used a DRUG that would render the person highly suggestible to hypnosis -- getting them to do whatever he wanted

So out of curiosity, I decided to google this and see if there were such a drug that could be used for mind control [not that a TV show would need to use something that really exists]

But it turns out there IS a drug called the "Devil's Breath" that is easily administered by powder and liquid, put into someone's drink or blown into their face in a second.   A few minutes later, subject is awake and alert but THEY HAVE NO FREE WILL and are totally helpless to other's suggestions.  Others have complete control over "an unwilling participant."  After it's over, it CAUSES COMPLETE AMNESIA.  [it has been around forever -- we haven't heard about it because the US gov't has been using for a long time]  CRAZY!!

Pretty scary actually.  Readily available in Columbia.
