Doctors introducing drug study somewhere in Germany (7)
I believe the answer is:
dresden
'in germany' is the definition.
(I know that Dresden is part of Germany)
'doctors introducing drug study somewhere' is the wordplay.
'doctors' becomes 'Drs' ('Dr' can be a synonym of 'doctor').
'introducing' is an insertion indicator (some letters introduced or inserted into others).
'drug' becomes 'e' (E is another name for ecstasy).
'study somewhere' becomes 'den' (term for a study or office. I am not sure about the 'somewhere' bit.).
'drs' enclosing 'e' is 'dres'.
'dres'+'den'='DRESDEN'
Can you help me to learn more?
(Other definitions for dresden that I've seen before include "'German city, almost totally destroyed by British air raids in 1945 (7)'" , "Germany city - reddens (anag)" , "Type of china" , "Famous china made at Meissen" , "SE German city" .)
