Student not involved in small cigar craze (5)
I believe the answer is:
mania
'craze' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for mania that I've seen before include "Obsessional enthusiasm" , "Madness - craze" , "Passion -- mood disorder" , "fixation" , "serious obsession" .)
