Synthetic pot and the 1960s military

In the 1960s, retired US Army colonel James S. Ketchum led efforts to develop a nonlethal incapacitating agent as a weapon for a "war without death." Along with LSD, they experimented with synthetic cannabis, apparently similar in effect to hash oil but much stronger. Alternet published a great profile of Ketchum who paints a vivid picture of those strange daze with the Us Army Chemical Corp. From Alternet:
In an interview videotaped seven hours after he had been given EA 2233, one soldier described feeling numb in his arms and unable to raise them, precluding any possibility that he could defend himself if attacked. "Everything seems comical," he told his interlocutor.

Q: How are you?

A: Pretty good, I guess. ...

Q: You've got a big grin on your face.

A: Yeah. I don't know what I'm grinning about, either.

Q: Do things seem funny, or is that just something you can't help?

A: I don't -- I don't know. I just -- I just feel like laughing. ...

Q: Does the time seem to pass slower or faster or any different than usual?

A: No different than usual. Just -- just that I mostly lose track of it. I don't know if it's early or late.

Q: Do you find yourself doing any daydreaming?

A: Yeah. I'm daydreaming all kinds of things. ...

Q: Suppose you have to get up and go to work now. How would you do?

A: I don't think I'd even care.

Q: Well, suppose the place were on fire?

A: It would seem funny.
