Cheaper drugs distributed: more potent (12)
I believe the answer is:
supercharged
'more potent' is the definition.
(I've seen this before)
'cheaper drugs distributed' is the wordplay.
'distributed' is an anagram indicator.
'cheaper'+'drugs'='cheaperdrugs'
'cheaperdrugs' with letters rearranged gives 'SUPERCHARGED'.
(Other definitions for supercharged that I've seen before include "Very quick" , "More potent" .)
