Answer: UKELELE
Explanation: Here fashion mag contains tab for stringed instrument (7)
An envelope ('contains') of E ('tab', an abbreviation for tablet, which makes a change from 'drug',) in UK ('here' if you happen to be in the UK; presumably Picaroon was when he wrote this) plus ELLE ('fashion mag'). An alternate spelling of UKULELE.
