In the last 20 years there have been numerous changes evidentamong the populationwho use substances whether this be alco‐hol or other drugs Themost important changes appear to be anincrease in the number of older drugs users a subsequent rise inrates of death from non‐drug related conditions (Beynon 2010)anincreaseinalcohol‐relatedmorbidityamongolderusers(Kaplanetal2012)and theburgeoningofNewPsychoactiveSubstances(NPS) use The increase in older drug users may be associatedwith changes to the treatmentmanagement for illicit opiateusersin the1990rsquos (McKeganey2006) and inparticular theexpansionandgreateravailabilityofmethadoneprescription (Clausen2008ClausenWaalThoresenampGossop2009)Thisincreasedavailabil‐itymeansthatincreasingnumbersofpeoplewithcurrentandprevi‐oussubstanceusehavebettersurvivalratesandaremorelikelytodiefromthesamechronicconditionsthataffectthegeneralpopu‐lation(Corkery2008Beynonetal2010)Itmaybethatsomeofthispopulationareusingsubstancesforlongerorcommencingdruguselaterinlifebutwhateverthecausetherehasbeenanincreasein older drug users accessing drug treatment services in the UK(Beynon2010Beynonetal2010)
