Admit in court, taking drug occasionally (6)
I believe the answer is:
induct
'admit' is the definition.
(I know that induct is a kind of admit)
'in court taking drug occasionally' is the wordplay.
'court' becomes 'ct' (abbreviation used in road names).
'taking' indicates putting letters inside.
'occasionally' indicates alternate letters (letters taken at regular intervals or occasions).
The alternate letters of 'drug' are 'du'.
'in'+'ct'='inct'
'inct' going around 'du' is 'INDUCT'.
(Other definitions for induct that I've seen before include "Formally admit (to a post or organisation)" , "Bring or lead in as for initiation" , "Bring formally into organisation, initiate" , "Admit as a member" , "Introduce" .)
