This article investigates patterns of drinking and drinking outcomes among
753 drug-misusing clients recruited to the National Treatment Outcome Resea
rch Study (NTORS). More than one third of those who were drinking at intake
reported problematic or highly problematic patterns of alcohol consumption
. About one third of the sample were abstinent from alcohol at intake and a
t follow-up. Some improvements in drinking behavior were found at I-year fo
llow-up, especially among the heaviest and most problematic drinkers. Impro
vements were specifically related to patterns of preintake drinking behavio
r. The majority of clients made little change to their pattern of pretreatm
ent drinking behavior and the continued heavy drinking of many drinkers at
follow-up is a disappointing finding. Drinking problems have been given ins
ufficient attention in the treatment of illicit substance misuse problems,
and efforts should be made to develop and strengthen the assessment and tre
atment of drinking problems among drug misusers. (C) 2000 Elsevier Science
