Tips from Aldous equipped with drugs in mixture (8)
I believe the answer is:
assorted
'in mixture' is the definition.
'tips from aldous equipped with drugs' is the wordplay.
'tips from' suggests removing the centre.
'equipped with drugs' becomes 'sorted' (slang term).
'aldous' with its middle removed is 'as'.
'as'+'sorted'='ASSORTED'
(Other definitions for assorted that I've seen before include "Of different kinds put together, like sweets" , "Mixed" , "Of various types put together" , "Classified" , "Miscellaneous, sundry" .)
