Crafty types producing drugs for peer groups, it's said

'crafty types' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'drugs for peer groups it's said' is the wordplay.
I cannot quite understand how this works, but
'drugs' could be 'ee' (I've seen this in other clues) and 'ee' is present in the answer.
'it's' could be 'ts' (abbreviation. e.g. in 'tis) and 'ts' is present in the answer.
This may be the basis of clue (or it may be nonsense).

'producing' is the link.

Can you help me to learn more?
