The availability of web sites offering to sell opioid medications without prescriptions.

OBJECTIVE: This study was designed to determine the availability of web sites offering to sell opioid medications without prescriptions. METHOD: Forty-seven Internet searches were conducted with a variety of opioid medication terms, including "codeine," "no prescription Vicodin," and "OxyContin." Two independent raters examined the links generated in each search and resolved any coding disagreements. The resulting links were coded as "no prescription web sites" (NPWs) if they offered to sell opioid medications without prescriptions. RESULTS: In searches with terms such as "no prescription codeine" and "Vicodin," over 50% of the links obtained were coded as "NPWs." The proportion of links yielding NPWs was greater when the phrase "no prescription" was added to the opioid term. More than 300 opioid NPWs were identified and entered into a database. CONCLUSIONS: Three national drug-use monitoring studies have cited significant increases in prescription opioid use over the past 5 years, particularly among young people. The emergence of NPWs introduces a new vector for unregulated access to opioids. Research is needed to determine the effect of NPWs on prescription opioid use initiation, misuse, and dependence.

Evaluation of full vs. partial continuum of care in the treatment of publicly funded substance abusers in Washington State.

This study evaluated the relative effectiveness of two forms of publicly funded substance abuse treatment provided in Washington State: The full continuum (FC), in which clients receive approximately three weeks of inpatient treatment prior to outpatient care, and the partial continuum (PC), in which clients are admitted directly to outpatient treatment. Data on treatment process/proximal outcomes, such as psychological distress and readiness to change, were assessed at 8 weeks post intake, and data on treatment services received were obtained at 2, 4, 8, and 12 weeks. Multidimensional outcomes, including alcohol and drug use as well as a number of psychosocial functioning outcomes, were assessed at 3 and 9 months post intake. Results indicated that clients in the FC had greater alcohol, drug, and legal problem severity at intake than those in the PC, whereas medical and employment problem severity was greater in the PC. Clients in the FC received more treatment services in the first 2 weeks than those in the PC, but there were no differences at subsequent points. Outcome analyses at 3 and 9 months indicated that clients in the FC had greater improvements in alcohol, drug, and psychiatric severity than those in the PC. Matching analyses indicated that clients with greater substance-use severity at baseline improved to a greater degree in the FC as compared to the PC. Matching effects were not obtained with medical or psychiatric severity, or readiness to change.
