A positive drug test at start of treatment predicts poor outcomes for stimulant users. But very limited information is available regarding the characteristics of these patients or the significance of early treatment drug use versus abstinence for those with other drug problems. Baseline data from a National Drug Abuse Treatment Clinical Trials Network study (protocol CTN-0044, "Web Delivery of Evidence-Based, Psychosocial Treatment for Substance Use Disorders") was used to explore these questions. Adults (N=494) presenting for outpatient psychosocial counseling treatment at 10 regionally diverse community treatment sites who agreed to participate in a randomized clinical trial of a new web-based psychosocial intervention were classified according to the primary problem drug they identified at treatment entry. Participants were further categorized as positive or negative for their primary drug at study baseline based on: self-reported recent alcohol use or urinalysis testing of marijuana, cocaine/other stimulants, and opiates. Drug negative and positive subgroups did not differ on demographic variables, but consistent with urine testing data, they differed on self-reported recent drug use. A smaller proportion of alcohol negative (20%) than positive (50%) participants' urine tested positive for one or more secondary drugs. Similarly, 18% of drug negative vs. 51% of drug positive cocaine/other stimulants users had evidence of using one or more secondary drugs. Recent 12-step involvement was reported by 69% and 40% of negative vs. positive alcohol users and by 74% and 49% of negative vs. positive cocaine/other stimulants users.

Conclusions: Early treatment of drug abstinence is common across all classes of primary drugs. Those abstaining from their primary drug are less likely to be actively using a secondary drug and more likely to be involved with a 12-step program at treatment entry. These findings suggest individual behavioral differences at treatment start that could inform treatment planning. (Poster, PDF, English, 2013)
