I agree with szuko000 in that even from my personal experience it tends to make you SO open to suggestion. However, following the good points 1000W made: it will be very unreliable and by all means not like a magical bullet that will instantly help you achieve anything like that you would want.
Reminds me of that video of British soldiers on LSD who start laughing and climbing trees and just scatter tripping balls (alas we cannot post the video here but just search), no - orders, that is: explicit orders, will be profoundly questioned or just not understood probably ^ .
Commands are the poorest way to brainwash a person though. Haven't you seen Inception?! (lol) If you indoctrinate a person in a cult-like way, LSD may be abused as an aid in such a 'scheme' and has been done so by Manson and that whole Skinner / Crystal Cole story?
Anyway, conclusion is that NO you cannot and should not do that - don't try to follow in the footsteps of psychos who we apparently born to manipulate people and the minds of already naieve / gullible persons. It just won't work, I think on some level the person will have to be able to and want to believe what ideas you are trying to feed them. Which is why it seems pointless on enemies if you are an intelligence agency I think.
It would probably torture them even more, if you feed them acid while already on a '24/7 sesame street blasting @ 100% volume' regimen in gitmo.
This thread should not be allowed to remain open? Though only to make clear what a terrible and shameful idea it is, on top of that it won't work.
