Without me, men get into bad habits and drink (7)
I believe the answer is:
absinth
'drink' is the definition.
(absinth is a kind of drink)
'without me men get into bad habits' is the wordplay.
'without' indicates named letters should be taken away.
'get into' means one lot of letters goes inside another.
'bad' is an anagram indicator.
'men' with 'me' taken away is 'n'.
'habits' is an anagram of 'absith'.
'n' inserted inside 'absith' is 'ABSINTH'.
'and' acts as a link.
(Other definitions for absinth that I've seen before include "sort of liqueur" , "Aniseed-flavoured liqueur" , "Bitter green liqueur" , "Strong liquor in baths, strangely" , "(Originally) a wormwood-based liqueur" .)
