Incarceration and drug use patterns among a cohort of injection drug users

ADDICTION, Issue 1 2009
Kora DeBeck
ABSTRACT Aims Drug law enforcement remains the dominant response to drug-related harm. However, the impact of incarceration on deterring drug use remains under-evaluated. We sought to explore the relationship between incarceration and patterns of drug use among people who inject drugs (IDU). Design Using generalized estimating equations (GEE), we examined the prevalence and correlates of injection cessation among participants in the Vancouver Injection Drug User Study followed over 9 years. In subanalyses, we used McNemar's tests and linear growth curve analyses to assess changes in drug use patterns before and after a period of incarceration among participants reporting incarceration and those not incarcerated. Findings Among 1603 IDU, 842 (53%) reported injection cessation for at least 6 months at some point during follow-up. In multivariate GEE analyses, recent incarceration was associated negatively with injection cessation [adjusted odds ratio (AOR) = 0.43, 95% confidence interval (CI) 0.37,0.50], whereas the use of methadone was associated positively with cessation (AOR = 1.38, 95% CI 1.22,1.56). In subanalyses assessing longitudinal patterns of drug use among incarcerated individuals and those not incarcerated over the study period, linear growth curve analyses indicated that there were no statistically significant differences in patterns of drug use between the two groups (all P > 0.05). Conclusions These observational data suggest that incarceration does not reduce drug use among IDU. Incarceration may inhibit access to mechanisms that promote injection cessation among IDU. In contrast, results indicate that methadone use is associated positively with injection cessation, independent of previous frequency of drug use. [source]

Aggressive behavior, related conduct problems, and variation in genes affecting dopamine turnover

AGGRESSIVE BEHAVIOR, Issue 3 2010
Elena L. Grigorenko
Abstract A number of dopamine-related genes have been implicated in the etiology of violent behavior and conduct problems. Of these genes, the ones that code for the enzymes that influence the turnover of dopamine (DA) have received the most attention. In this study, we investigated 12 genetic polymorphisms in four genes involved with DA functioning (COMT, MAOA and MAOB, and D,H) in 179 incarcerated male Russian adolescents and two groups of matched controls: boys without criminal records referred to by their teachers as (a) "troubled-behavior-free" boys, n=182; and (b) "troubled-behavior" boys, n=60. The participants were classified as (1) being incarcerated or not, (2) having the DSM-IV diagnosis of conduct disorder (CD) or not, and (3) having committed violent or nonviolent crimes (for the incarcerated individuals only). The findings indicate that, although no single genetic variant in any of the four genes differentiated individuals in the investigated groups, various linear combinations (i.e., haplotypes) and nonlinear combinations (i.e., interactions between variants within and across genes) of genetic variants resulted in informative and robust classifications for two of the three groupings. These combinations of genetic variants differentiated individuals in incarceration vs. nonincarcerated and CD vs. no-CD groups; no informative combinations were established consistently for the grouping by crime within the incarcerated individuals. This study underscores the importance of considering multiple rather than single markers within candidate genes and their additive and interactive combinations, both with themselves and with nongenetic indicators, while attempting to understand the genetic background of such complex behaviors as serious conduct problems.

PTSD symptoms, substance use, and vipassana meditation among incarcerated individuals

JOURNAL OF TRAUMATIC STRESS, Issue 3 2007
T. L. Simpson
The present study evaluated whether Posttraumatic Stress Disorder (PTSD) symptom severity was associated with participation and treatment outcomes comparing a Vipassana meditation course to treatment as usual in an incarcerated sample. This study utilizes secondary data. The original study demonstrated that Vipassana meditation is associated with reductions in substance use. The present study found that PTSD symptom severity did not differ significantly between those who did and did not volunteer to take the course. Participation in the Vipassana course was associated with significantly greater reductions in substance use than treatment as usual, regardless of PTSD symptom severity levels. These results suggest that Vipassana meditation is worthy of further study for those with comorbid PTSD and substance use problems. [source]

Medical and psychiatric problems among men and women in a community corrections residential setting

BEHAVIORAL SCIENCES & THE LAW, Issue 5 2009
Tracy D. Gunter M.D.
Though the medical and mental health morbidity of incarcerated offenders has been discussed in a number of recent reports, very few data have been published concerning medical and mental health problems facing those on community corrections supervision. In this study of community corrections offenders utilizing residential facilities, we found that frequencies of substance use disorders, other mental health disorders, and medical problems exceeded frequencies found in the community and, in some cases, were higher than frequencies found in incarcerated individuals. Of particular concern were the high frequencies of substance use disorders, traumatic brain injury, anxiety states, suicidal ideation, and prior self-harm. While the level of self-reported medical and mental health service utilization was higher than expected, it appeared low relative to the disease burden reported by this special population. We conclude that concurrent evaluation and treatment of medical and psychiatric problems during the process of community supervision is indicated in this population.
