One answer and two explanations please.
8d. Does perhaps rush from south to north (4) D?E?

And
14d. Collapsed case of bloke clearly taking cocaine to be used again (10)
Has to be Recyclable but cant see the wordplay
29a. Comfortable place with standards? (3,2,5)
I've got "bed of roses" but don't understand the standards bit.

29 - standard roses.....

Deer

Reed (rush) backwards

Does = Deer

14d collapsed indicates anagram of: case of BlokE = BE, CLEARLY, C for cocaine

[dr b]

Case (outside) of BlokE + CLEARLY + C, anagrammed

Thank you all. I hadn't heard of Standard roses before but thanks to the power of Google [other search engines are available] I am now a little wiser.
I knew there was an anagram in 14 but I couldn't have found it without your help and I've been caught out on the Rush Reed thing before.
I'm learning... slowly
