OBJECTIVES Alcohol screening and brief interventions in medical settings can significantly reduce alcohol use. Corresponding data for illicit drug use is sparse. A Federally funded screening, brief interventions, referral to treatment (SBIRT) service program, the largest of its kind to date, was initiated by the Substance Abuse and Mental Health Services Administration (SAMHSA) in a wide variety of medical settings. We compared illicit drug use at intake and 6 months after drug screening and interventions were administered. DESIGN SBIRT services were implemented in a range of medical settings across six states. A diverse patient population (Alaska Natives, American Indians, African-Americans, Caucasians, Hispanics), was screened and offered score-based progressive levels of intervention (brief intervention, brief treatment, referral to specialty treatment). In this secondary analysis of the SBIRT service program, drug use data was compared at intake and at a 6-month follow-up, in a sample of a randomly selected population (10%) that screened positive at baseline. RESULTS Of 459,599 patients screened, 22.7% screened positive for a spectrum of use (risky/problematic, abuse/addiction). The majority were recommended for a brief intervention (15.9%), with a smaller percentage recommended for brief treatment (3.2%) or referral to specialty treatment (3.7%). Among those reporting baseline illicit drug use, rates of drug use at 6-month follow-up (4 of 6 sites), were 67.7% lower (p<0.001) and heavy alcohol use was 38.6% lower (p<0.001), with comparable findings across sites, gender, race/ethnic, age subgroups. Among persons recommended for brief treatment or referral to specialty treatment, self-reported improvements in general health (p<0.001), mental health (p<0.001), employment (p<0.001), housing status (p<0.001), and criminal behavior (p<0.001) were found. CONCLUSIONS SBIRT was feasible to implement and the self-reported patient status at 6 months indicated significant improvements over baseline, for illicit drug use and heavy alcohol use, with functional domains improved, across a range of health care settings and a range of patients.

When to begin smoking cessation in substance abusers

Karen L. Sees; H. Westley Clark

During the past several years, there has been an increasing recognition and acceptance that the use of tobacco products often produces nicotine dependence and nicotine addiction. Despite this, the substance abuse treatment community has been slow to promote smoking cessation for patients who are in substance abuse treatment for another addiction. Dogma, although starting to change, persists that cigarette smoking pales in comparison to other addictions and should not be addressed at the time of initial treatment for another addiction. The limited research to date, which will be reviewed in this article, does not support this dogma. In addition, patients presenting for substance abuse treatment report high interest in stopping smoking, including interest in stopping when they initially present for substance abuse treatment.

Opioid use in the treatment of chronic pain: Assessment of addiction

Karen L. Sees; H. Westley Clark

Addiction medicine specialists, besieged with the adverse consequences of opioids, not unreasonably develop reservations about their use. Opioid prohibition may be appropriate when working with addicts, but drug abstinence is not always the most appropriate nor optimal treatment of pain patients. Consultation concerning the management of chronic pain patients may require an attitude adjustment of challenging proportions for the addiction medicine specialist; it is a role substantially different from that usually assumed in treating alcohol- and drug-dependent patients. Rather than relentlessly pursuing psychotropic drug abstinence as the treatment goal, restoration of function should be the primary treatment goal for the chronic pain patient. Unlike the chemically dependent patient whose level of function is impaired by substance use, the chronic pain patients level of function may improve with adequate, judicious use of medications, which may include opioids. Evaluating for addiction in a patient who is prescribed long-term opioids for pain control is often problematic. While the concept of addiction may include the symptoms of physical dependence and tolerance, physical dependence and/or tolerance alone does not equate with addiction. In the chronic pain patient taking long-term opioids, physical dependence and tolerance should be expected, but the maladaptive behavior changes associated with addiction are not expected. Thus, it is the presence of these behaviors in the chronic pain patient that is far more important in diagnosing addiction.

Violent traumatic events and drug abuse severity

H. Westley Clark; Carmen L. Masson; Kevin Delucchi; Sharon M. Hall; Karen L. Sees

We examined the occurrence of violent traumatic events, DSM-III-R diagnosis of posttraumatic stress disorder (PTSD), and PTSD symptoms, and the relationship of these variables to drug abuse severity. One-hundred fifty opioid-dependent drug abusers who were participants in a randomized trial of two methadone treatment interventions were interviewed using the Diagnostic Interview Schedule, the Addiction Severity Index, and the Beck Depression Inventory. Twenty-nine percent met diagnostic criteria for PTSD. With the exception of rape, no gender differences in the prevalence of violent traumatic events were observed. The occurrence of PTSD-related symptoms was associated with greater drug abuse severity after controlling for gender, depression, and lifetime diagnosis of PTSD. The high rate of PTSD among these methadone patients, the nature of the traumatic events to which they are exposed, and subsequent violence-related psychiatric sequelae have important implications for identification and treatment of PTSD among those seeking drug abuse treatment.

Traumatic Experiences and Substance Abuse: Mapping the Territory

Joan E. Zweben; H. Westley Clark; David E. Smith

This article examines the relationships between various types of traumatic experiences and addictive behavior, with an eye to formulating effective treatment strategies. Interventions in the posttraumatic stress disorder (PTSD) and related fields are reviewed in an effort to understand how best to integrate them into substance abuse treatment. The recovery-oriented therapy model is used as a framework to define treatment tasks at each stage of the recovery process: how one addresses painful issues depends on the objective, given the recovery stage at hand. These tasks include making a commitment to abstinence, stopping alcohol and other drug use, consolidating abstinence and changing lifestyles, and addressing short- and long-term psychosocial issues. The article focuses on the clinical features of PTSD in an effort to enhance the practitioners ability to address this disorder within the context of substance abuse treatment. Finally, recommendations are offered for training practitioners at varying skill levels in the addiction treatment field.

Anger Management and Temper Control: Critical Components of Posttraumatic Stress Disorder and Substance Abuse Treatment

Patrick M. Reilly; H. Westley Clark; Michael S. Shopshire; Ervin W. Lewis; Donna J. Sorensen

Recent studies have shown associations among combat experience, PTSD, anger and hostility, and involvement in violence. Clinical observations of veterans enrolled in the Substance Use/Posttraumatic Stress Disorder Team (SUPT) program at the San Francisco Veterans Affairs Medical Center revealed relatively high levels of anger and aggressive behavior, including physical assaults and property damage. In response to this anger and aggressive behavior, an anger management treatment was added to the SUPT programs treatment of substance abuse and PTSD. Anger management consisted of a 12-week cognitive-behavioral group treatment. Session topics included identifying the physical, emotional, and situational cues to anger, developing individualized anger-control plans, recognizing and altering destructive self-talk, utilizing time-out, practicing conflict resolution techniques, and using the group to discuss and evaluate high-risk anger situations. Special attention was given to self-monitoring anger-escalating behavior (using an anger meter) and avoiding negative consequences. This article describes the components of the anger management treatment. A clinical vignette is also presented to illustrate the benefits of anger management treatment.

Buprenorphine (BPN) is a prescription analgesic with mixed opioid agonist and antagonist properties. This pilot study conducted detailed case studies with 15 methadone dependent patients. The study sought to determine whether repeated low doses (0.15 to 0.3 mg) of sublingual BPN would relieve opioid withdrawal symptoms. Subjects developed mild to moderate withdrawal symptoms within 26 to 31 hours of methadone discontinuation. Once in withdrawal, the subjects received 0.15 mg of BPN sublingually. A second dose of 0.15 mg was administered in an hour, and a 0.30 mg dose in 2 hours, if the subject obtained no relief of withdrawal symptoms. In 6 subjects a low dose of 0.15 to 0.30 mg sublingual BPN resulted in the disappearance of subjective and objective withdrawal symptoms within 10 minutes to 2.5 hours. Four others had brief, partial relief of symptoms. Five subjects failed to experience any relief of withdrawal symptoms after a total of 0.6 mg BPN administered over 3 hours. One nonresponder suffered what appeared to be a severe precipitated withdrawal reaction similar to that which can be produced in addicts by a naloxone challenge. The 4 Caucasian responders required 1 to 2 hours to respond to BPN, whereas the 2 African-American responders required only 10 to 20 minutes. Low (analgesic) doses of BPN were sufficient to treat all methadone withdrawal symptoms in 6 of 15 subjects. There may be ethnic differences in response to BPN. Low dose BPN may play a role in carefully monitored heroin detoxification treatment.

We measured hippocampal volumes and cognitive functioning in crack‐cocaine and crack‐cocaine/alcoholdependent subjects (abstinent approximately 10–12 weeks) compared to age‐matched controls. Cognitive function was evaluated using the computerized MicroCog Assessment of Cognitive Functioning (which includes tests of explicit, declarative memory subserved by the hippocampus). The hippocampal volumes were quantified on T1‐weighted MRIs and were expressed as a proportion of intracranial vault volume. Both subjects and controls showed the larger right versus left hippocampal volume expected in normal anatomy, but we found no differences in hippocampal volume between any of the groups. However, both abstinent cocaine‐dependent subjects and abstinent cocaine/alcohol‐dependent subjects showed persistent cognitive impairments, including deficits in explicit memory. Our results suggest that either: (1) the hippocampus is resistant to structural volume loss in young and middle‐aged cocaine or cocaine/alcohol‐dependent subjects, (2) the hippocampal volume loss suffered by young and middle‐aged cocaine or cocaine/alcohol‐dependent subjects resolves after approximately 3 months of abstinence, or (3) hippocampal atrophy is obscured by the process of gliosis. Further, the cognitive impairments persisting in these abstinent cocaine and cocaine/alcohol‐dependent samples may (1) be unrelated to hippocampal function or (2) be associated with abnormal hippocampal function that is not reflected in MRI measures of overall hippocampal atrophy.

This article traces the history of the Recovery Community Services Program (RCSP) from its inception in the Substance Abuse Mental Health Services Administration/Center for Substance Abuse Treatment (SAMHSA/CSAT) 1998 vision of communities of recovery engaged in the public dialogue about addiction, treatment, and recovery through the 2002 programmatic refocus onto the provision of social supports for recovery, designed and delivered by people who share the experience of addiction and recovery, that is, peers. It focuses on the role of peer-to-peer recovery support services in an evolving recovery-oriented system of care, lessons learned as the grant program has matured, and continuing challenges in this latest chapter of the ongoing history of the relationship between communities of recovery and formal systems of care. Following articles represent how these principles are embodied in RCSP communities across the nation.

A Case Study in Collaborating with Atlanta-Based African-American Churches: A Promising Means for Reaching Inner-City Substance Users with Rapid HIV Testing

David L. Whiters; Scott Santibanez; David Dennison; H. Westley Clark

This case study examined programmatic data from a federally funded faith-based rapid HIV testing initiative. In 2004, Recovery Consultants of Atlanta, Inc. (RCA, Inc.) began providing rapid HIV testing in collaboration with six Atlanta-based African-American churches. Of the 1,947 persons tested from January 2004 to July 2005, 1,872 (96.1%) were African-American, 1,247 (64%) were male, and 1,612 (82.8%) were between the age of 26 and 56. A total of 85 HIV-infected individuals were identified and 72 were identified as previously undiagnosed cases (positivity rate of 3.7%). This case study highlights and promotes rapid HIV testing offered in partnership with African American churches as a strategy for raising HIV awareness among inner-city substance users.
