The detailed tables published by ONS in September 2015 on drug-related poisoning deaths did not include as much detail as in previous years in terms of specific substances mentioned in the cause of death field.

Is it possible, for 2014 registrations, to obtain the following, as given in previous FOI answers?

Number of any mention, sole mention, mention with alcohol (i.e. the same basis as Tables 6a-c) regarding these drugs:

GHB/GBL (I note that Note 9 on page 35 explains that GBL is included with the GHB figures)
Ketamine
Piperazines
Cathinones
Mephedrone
Khat
