Potter about, right before last of weed's smoked? (5)
I believe the answer is:
cured
'smoked?' is the definition.
(I've seen this before)
'potter about right before last of weed's' is the wordplay.
'potter' becomes 'cue' (a cue pots balls in snooker etc).
'about' indicates putting letters inside.
'right' becomes 'r' (common abbreviation).
'before' says to put letters next to each other.
'last of' indicates one should take the final letters.
The last letter of 'weed' is 'd'.
'cue' enclosing 'r' is 'cure'.
'cure'+'d'='CURED'
(Other definitions for cured that I've seen before include "Rehabilitated" , "Healed - preserved" , "Made healthy again" , "Successfully treated" , "Freed of disease" .)
