The work of the Center is carried out through clinical trials that investigate causes of substance use disorders and investigate novel treatments. These findings in these studies often affect the way treatment is delivered in actual healthcare environments.

The purpose of this study is to evaluate the the effect of medical marijuana (MM) on a range of outcomes, including clinical symptoms, cognitive performance, brain function, and possible transition to cannabis use disorders (CUD), in adults who are interested in using medical marijuana to treat pain, insomnia, depression, or anxiety. We will conduct longitudal assessments over 6 months that will: (1) characterize the impact of MM on progression to CUD, as well as other indices of addiction such as increased tolerance and withdrawal among those who stop using MM, (2) assess, via daily dosing diaries, the effect of MM use patterns on use of other medications and perception of underlying disease symptomatology, (3) characterize the impact of MM on neurocognitive performance, including executive function, memory, attention, and decision-making and (4) examine evidence for impact of MM on brain function in the prefrontal cortex and reward regions.
The aims of this study are to characterize the most common illnesses for which MM is sought, the reasons for seeking MM, reasons for hesitance to use and to characterize current marijuana use habits of those interested in using MM.
The purpose of this study is to provide updated information on prevalence and frequency of cannabis use in relation to other forms of substance use in a representative sample of high-school aged adolescents, to evaluate the effect of contingency management on initial 30-day verified cannabis abstinence in adolescents and older adolescents who use cannabis at least weekly and are not seeking treatment, to determine whether there is cognitive dysfunction in cannabis use that persists in the short term (4 days) after use but resolves with extended abstinence (30 days) compared to cannabis users who do not quit and non-using controls and to estimate the rate of cognitive improvement with cannabis abstinence as a function of time since last use and concentration of detectable cannabis metabolites in urine.
This grant is designed to develop specific content expertise in treatment and recovery policy, and the design, implementation, and evaluation of treatment and recovery support service combinations. This grant also allows for mentoring junior investigators in patient-orientated addiction research (POAR).
The aim of the study is to design novel behavioral tasks that will allow us to separate and empirically measure factors that predict social influence. We would like to design new tasks based on classic psychological studies that will allows us to model social influence, to observe differences between non-dependent young adults aged 18-25 who use either alcohol (ALC) or marijuana (MJ), and age-matched controls (CON), in order to investigate differences in susceptibility to social influence and in neural activation of regions associated with social influence as a function of early drug use.
The aim of this study is to assess the effects of THC intoxication using the medication dronabinol (synthetic THC) on resting state and task-based activation in the prefrontal cortex (PFC), as well as on neurocognitive task performance and correlations between these measurements and clinical signs of intoxication, as well as to investigate at which doses of dronabinol an effect on neurocognitive task performance or an effect on PFC activity can be observed.

This study aims to determine whether smokers have increased expression of dopamine D2/D3 receptors than do non-smokers and whether there is an association between D2/D3 expression, as measured with positron emission tomography, and functional MRI reactivity to smoking cues, which, when increased, predicts relapse to smoking after initial abstinence.
This project proposes to conduct an open-label, four-site randomized controlled trial of a fixed-dose, combination of drugs versus usual treatment for the prevention of cardiovascular disease among patients receiving second-generation antipsychotic drugs for severe mental illness. The trial assesses the effectiveness of an initial treatment strategy using moderate doses of HMG-Co A reductase inhibitors and angiotensin receptor blockers which have proven efficacy and safety. We will test this treatment strategy within mental health clinics.

This study is using a combined data set consisting of the data collected at MGH by Dr. Evins from a study population of smokers with SMI and a study with a comparable study design conducted at Pfizer in a population of smokers without SMI. The aim is to test the hypotheses that smokers without SMI will achieve a higher proportion of continuous tobacco abstinence during the maintenance of smoking cessation phase (i.e., in the 12 weeks post randomization, study weeks 12-24) than smokers with SMI, but this diagnosis effect will be normalized (i.e., will not be apparent) in the active pharmacotherapy (i.e., varenicline) group; smokers without SMI will have a longer mean time to relapse than smokers with SMI, and this difference will be greatest under placebo conditions and less pronounced in participants receiving active pharmacotherapy (varenicline) and that smokers without SMI will achieve a higher proportion of biochemically validated 7-day point prevalence tobacco abstinence during active, open-label treatment with varenicline than smokers with SMI, even after adjusting for baseline differences in age, gender, severity of nicotine dependence, cigarettes smoked per day, age of onset of daily smoking.

This is the first randomized controlled study on the effectiveness of a treatment combining Cognitive Behavioral Therapy and Brief Motivational Intervention (CBT+BMI) for college students with depressive symptoms who binge drink. Given the severe consequences associated with binge drinking and depressive symptoms in college students identifying an effective treatment for this population has critical public health significance. The Treatment for Excessive Alcohol Use and Depression in Students (TREADS) study lasts approximately 12 weeks. As part of the study participants complete a baseline visits and then are randomized, by chance, like the flip of a coin, to one of two therapy programs. Both courses include eight therapy visits and teach coping skills for depressive symptoms. However, in one therapy program participants receive a personalized feedback about their alcohol use, while in the other program they may or may not talk about alcohol consumption depending on the students’ preference. Both courses teach the same coping skills for depressive symptoms but include different levels of focus on alcohol. Participants complete one follow-up assessment visit at the end of the therapy program and one four weeks later. The three assessment visits are reimbursed.
