Clyde Craig is crazy for hallucinogenic drug (8,4)

I believe the answer is:

lysergic acid

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

'hallucinogenic drug' is the definition.
'lysergic acid' can be an answer for 'drug' (I've seen this before). I am unsure of the 'hallucinogenic' bit.

'clyde craig is crazy' is the wordplay.
'crazy' indicates anagramming the letters.
'clyde'+'craig'+'is'='clydecraigis'
'clydecraigis' is an anagram of 'LYSERGIC ACID'.

'for' acts as a link.

Can you help me to learn more?

(Another definition for lysergic acid that I've seen is " Drug".)

I've seen this clue in the Sydney Morning Herald.
