Stupidly I take men a hallucinogen (8)

I believe the answer is:

ketamine

I'm a little stuck... Click here to teach me more about this clue!

'a hallucinogen' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'stupidly i take men' is the wordplay.
'stupidly' indicates anagramming the letters (a stupid ordering of the letters).
'i'+'take'+'men'='itakemen'
'itakemen' anagrammed gives 'KETAMINE'.

Can you help me to learn more?

(Another definition for ketamine that I've seen is " Anaesthetic/analgesic sometimes used illegally".)

I've seen this clue in The Times.
