A perspective review of cannabis use and sexual offenses.

Substance abuse is an established risk factor for crime and violence, including sexual violence. Nevertheless, the link between cannabis use and sexual offenses remains poorly understood. Cannabis use has a broad effect on sexual functioning and can have both acute and lasting adverse effects on psychological functioning, which in turn can elevate the risk of sexual offending behavior. Yet there is a scarcity of studies that have examined the link between cannabis use and sexual offending. To help fill the gap, this perspective review investigates the link between substance use and crime with a particular emphasis on cannabis use and its effects on sexual and psychological functioning. It then explores how these mechanisms may contribute to sexual offenses and recidivism, with a final discussion on how cannabis use should be conceptualized as a risk factor for sexual violence.

Evaluating conditional release in not guilty by reason of insanity acquittees: a prospective follow-up study in Virginia.

Detailed research on treatment and risk management approaches with not guilty by reason of insanity acquittees (NGRI) during their conditional release is needed as states increasingly use community-based services for these individuals. Grounded in case law, and supported by follow-up studies demonstrating low recidivism rates, states have been encouraged in their efforts to conditionally release NGRI acquittees. The authors evaluated a state-wide sample of 127 NGRI acquittees released into the community after spending a mean of 61.63 months (SD = 76.54) in the hospital. One hundred individuals were committed to the hospital for lengthier treatment (M hospital time = 77.23 months, SD = 79.84), but 27 individuals were released to the community after a relatively short hospital stay (M hospital time = 5.60 months, SD = 3.01). Regarding release, 96 individuals (75.6%) maintained their conditional release. After evaluating a host of demographic and standardized risk data, the following variables predicted revocation on conditional release: previous failure on conditional release, nonadherence with hospital treatment, dangerousness to others, and previous violent charges. A multivariate survival analysis determined criminal behavior and previous failure on conditional release predicted time to revocation. The results of this study demonstrate the importance of considering standardized risk variables in the community-based management of forensic patients. In addition, the data are supportive of continued attempts at moving insanity acquittees from the hospital to the community via conditional release.

Unreasonable minds and imperfect self-defense.

Western legal systems recognize the right to self-defense as a right of individuals, under certain circumstances, to use physical force to defend themselves from an aggressor. This right requires an honest and reasonable belief of the person asserting it regarding the circumstances in which force is used. Some jurisdictions also permit a defense of imperfect self-defense, allowing for reduced culpability for the crime of homicide if a person's beliefs are honest but unreasonable. If the unreasonable belief is based on a mental illness, however, the defense is disallowed in every jurisdiction in the United States. This development relies upon an untenable position that false beliefs produced by mental disorders should be excluded based on erroneous assumptions about psychotic illness. This article argues that the current precedent is incoherent with the core structure of criminal responsibility and in tension with current scientific understandings and should change to do justice.

Criminal justice system involvement among people with schizophrenia.

There is growing concern that people with schizophrenia and other severe mental illnesses are increasingly at risk for unnecessary criminal justice system (CJS) involvement. There has been limited examination, however, of which individual characteristics predict future CJS involvement. This study uses data from the Clinical Antipsychotic Trials of Intervention Effectiveness on sociodemograhic characteristics, baseline clinical status, and service use among patients diagnosed with schizophrenia to prospectively identify predictors of CJS involvement during the following year. A series of bivariate chi-square and F tests were conducted to examine whether significant relationships existed between CJS involvement during the first 12 months of the trial and baseline measures of sociodemographic characteristics, psychiatric status, substance abuse, and other patient characteristics. Multivariate logistic regression analysis was then used to identify the independent strength of the relationship between 12-month CJS involvement and potential risk factors that were found to be significant in bivariate analyses. Multivariate logistic regression analyses indicated that past adolescent conduct disorder, being younger and male, symptoms of Akathisia (movement disorder, most often develops as a side effect of antipsychotic medications), and particularly drug abuse increase the risk for CJS involvement. Since CJS involvement among people with schizophrenia was most strongly associated with drug abuse, treatment of co-morbid drug abuse could reduce the risk of stigma, pain, and other adverse consequences of CJS involvement as well as save CJS expenditures.

Risk of incarceration between cohorts of veterans with and without mental illness discharged from inpatient units.

OBJECTIVE: This study examined the risk of incarceration among cohorts of veterans treated in the Department of Veterans Affairs (VA) Connecticut Healthcare System. Incarceration rates of persons with and without mental illness were compared and adjusted for various clinical and service utilization variables. Data were compared before and after the closure of over 80% of the Connecticut VA psychiatric inpatient beds in 1996. METHODS: Data from five annual cohorts of patients (1993-1997) treated in an inpatient unit in the VA Connecticut Healthcare System (N=36,385) were merged with state Department of Correction data. Logistic regression models were used to identify risk factors for incarceration. RESULTS: Bivariate analysis showed that incarceration rates were higher for VA patients with psychiatric disorders and with substance use disorders than for those without such diagnoses, but there were no significant increases in likelihood of incarceration over these years of extensive closures. In multiple logistic regression analysis only diagnoses of substance use disorders and major depression were independently associated with an increased likelihood of incarceration, whereas schizophrenia, personality disorders, and co-occurring psychiatric and substance use disorders were not independently associated with increased likelihood in multivariate analysis. CONCLUSIONS: Alcohol and drug problems appeared to account for much of the risk of incarceration among hospitalized veterans during the study period. Unlike in previous studies, schizophrenia and related psychotic disorders were not independently associated with an increased risk of incarceration.

Legal fallacies of antipsychotic drugs.

Advances in the biological sciences have dramatically improved the understanding of schizophrenia and related psychotic illnesses. One of the most compelling findings is the substantial degree to which cognition is impaired in these illnesses and the remedial effects that antipsychotic drugs have in treating these cognitive impairments. Despite these promising discoveries, legal cases and scholarship remain replete with pejorative associations with antipsychotic drug action. References to antipsychotic medications as mind-altering drugs and their effects as "synthetic sanity" misconstrue the beneficial effects these medicines have on cognition. We review the prevailing legal attitude of antipsychotic medications and contrast these views with prevailing scientific knowledge. We conclude that legal opinion is misinformed about the effects of antipsychotic medications on cognition.

Efficacy and tolerability of low-dose donepezil in schizophrenia.

There have been many advancements in the pharmacologic treatment of schizophrenia; however, negative symptoms and cognitive impairment remain an intractable part of this illness. Donepezil is an anticholinesterase inhibitor with cognitive enhancing effects approved for the treatment of Alzheimer disease that has shown some benefit in the treatment of schizophrenia. In this study, 15 inpatients at a state hospital with a history of schizophrenia were administered donepezil in a randomized, double-blind, crossover design. Neurocognitive testing and psychiatric ratings were completed at baseline and at regular intervals for 18 weeks. Results indicated that donepezil treatment was associated with modest improvements in psychiatric symptoms and improved verbal learning. These results suggest that donepezil may be helpful as adjunctive therapy for the treatment of psychiatric symptoms and cognitive impairment in a subgroup of schizophrenic patients.

Predictors of arrest during forensic assertive community treatment.

OBJECTIVE: An emerging adaptation of the assertive community treatment model is forensic assertive community treatment (FACT), which aims to prevent criminal recidivism. This study examined predictors of arrest among patients in a prototype program and considered the implications of study findings for future development of the FACT model. METHODS: Demographic and clinical data from all 130 patients treated in Project Link from 1997 through 2003 were merged with a statewide criminal record database to identify variables associated with arrest. RESULTS: Poisson regression revealed a history of arrests for violent offenses before treatment and evictions from residential treatment, and antisocial traits were associated with arrest during treatment. Substance abuse was not associated with arrest, but the sample lacked heterogeneity for this factor. CONCLUSIONS: Variables associated with arrest were similar to those seen in the general population. In the absence of a standardized model of intervention, FACT programs should incorporate interventions that target modifiable risk factors in order to prevent criminal recidivism among high-risk patients.

Variations in mental health courts: challenges, opportunities, and a call for caution.

Mental health courts have quickly proliferated in the United States and represent an attempt to expand legal leverage and enhanced treatment access to select persons with severe mental illness who are also involved in the criminal justice system. A national survey of mental health courts has begun to elucidate the procedural, clinical, and operational aspects of these courts and the defendants they adjudicate. A secondary analysis of survey data was performed to determine the similarities and differences among these courts. Results revealed large variability among existing mental health courts across multiple domains. The implications of this variability are discussed in terms benefits and limitations.

A retrospective examination of outpatient commitment in New York.

Outpatient commitment (OC) is a growing trend in mental health treatment. The impetus for this movement has been partly due to the public perception that some mentally ill outpatients are prone to violence as result of poor treatment compliance. Numerous studies have shown that poor treatment compliance is associated with increased hospitalization, substance abuse, homelessness, and contact with the criminal justice system. This study examined treatment effectiveness, demographic variables, hospital utilization, and violence among 100 OC participants in New York. Results indicate that OC can be an effective means of increasing treatment compliance and reducing hospitalization and encounters with the criminal justice system.
