Well that was fun. Took me ages to get the pdm.
Can anyone help me parse
1d: Village part-time vegetable store to bear investigation? Nonsense (7)
I cannot see how this works at all.
Also 37a: Considered giving up marijuana although, at first, possibly took heroin (4).
I have the first three letters from crossers, but don't get this one either, with its multiple possibilities for the fourth letter.
Thanks vm for any hints!
