Actress just lost way, used drug at new clubs, close to casbah (4,5)

'lost way used drug at new clubs close to casbah' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'actress' is the wordplay.
I cannot quite see how this works, but
'actress' could be 'dench' (I've seen this before) and 'dench' is found in the answer.
The remaining letters 'judi' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'just' is the link.

Can you help me to learn more?
