Sportsman attending hospital allowed to get drug (7)
I believe the answer is:
athlete
'sportsman' is the definition.
(thesaurus)
'attending hospital allowed to get drug' is the wordplay.
'attending' becomes 'at' (I've seen this in other clues**).
'hospital' becomes 'h'.
'allowed' becomes 'let' (I've seen this before).
'to get' is a charade indicator (letters next to each other).
'drug' becomes 'e' (e is another name for ecstasy).
'at'+'h'+'let'+'e'='ATHLETE'
(Other definitions for athlete that I've seen before include "Trained sportsperson" , "Bolt perhaps" , "Contestant" , "The tale (anag)" , "Runner, jumper, thrower" .)
