Stand experience of drug overdose (6)
I believe the answer is:
tripod
'stand' is the definition.
(tripod is a kind of stand)
'experience of drug overdose' is the wordplay.
'experience of drug' becomes 'trip' (as in tripping on drugs).
'overdose' becomes 'o.d.' (synonyms).
'trip'+'od'='TRIPOD'
(Other definitions for tripod that I've seen before include "oral test at school" , "Three-legged support" , "support called for" , "Something on three legs" , "one appears to have three legs!" .)
