Drug users mistakenly freed in talks (5,6)

'drug users' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'mistakenly freed in talks' is the wordplay.
'mistakenly' is an anagram indicator.
'in' means one lot of letters goes inside another.
'talks' becomes 'speaks' ('speak' can be a synonym of 'talk').
'freed' is an anagram of 'eedfr'.
'eedfr' put within 'speaks' is 'SPEED FREAKS'.

Can you help me to learn more?
