Best low-strength drug? (5)
I believe the answer is:
elite
'best' is the definition.
(elite can mean the very best of a group)
'low-strength drug?' is the wordplay.
I cannot really understand how this works, but
'drug?' could be 'e' (E is another name for ecstasy) and 'e' is located in the answer.
The remaining letters 'lite' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for elite that I've seen before include "Select body, cream" , "top drawer?" , "Pick of the bunch" , "Exclusive set" , "A privileged or select group" .)
