Adults (ages 18+) who use cannabis and are interested in reducing their use will be enrolled in an 8-week treatment program. All participants will receive counseling (1 goals session with a therapist followed by 7 weekly computerized cognitive-behavioral therapy sessions). Detailed cannabis assessments (biological and self-report) will be conducted throughout treatment and at 1- and 4-months post-treatment completion. Daily electronic diaries will be administered via text message to record detailed logs of cannabis use quantity and frequency. Participants are also asked at different points throughout the study to wear a Fitbit to monitor their sleep.

This is a 16-week-long treatment study for people with Alcohol Use Disorder who want to stop or cut down their drinking. The purpose of this study is to determine whether an investigational medication, TMP-301, affects craving for alcohol and/or alcohol drinking while taking the study drug. Participants will be randomly assigned to TMP-301or a matched placebo

This study will examine genetic factors that contribute to the different ways people feel after consuming cannabis. People that use cannabis at least 4 days per week will participate in a study involving 1 in-person visit followed by a 5-day remote assessment period. The in-person visit will determine if an individual is eligible for study participation and their blood will be drawn to assess genetics. During the remote assessment period, participants will complete multiple short surveys per day describing their feelings and their recent cannabis use.

The primary objective of this proposal is to conduct surveys and qualitative interviews to get feedback from (1) stakeholders and (2) people with lived experience of opioid use and a related medical hospitalization, on the barriers and facilitators of new potential strategy of treatment. The potential proposed intervention we will ask questions about is the direct mailing medications for opioid use disorder (OUD) in an attempt to overcome many of the barriers that interfere with treatment retention (i.e. transportation). Qualitative interviews will be used to get feedback on the feasibility, appropriateness, and acceptability of mailing maintenance medications for OUD after a hospital discharge. In a future study, this feedback will be used to develop a protocol to test this method.

This is a smoking cessation study which is examining varenicline for use in reducing or quitting e-cigarettes. Half of the participants will receive a placebo pill and half will receive varenicline. All participants will be asked to complete daily, brief REDCap EMA diaries (to report e-cigarette use, other tobacco use, and record videos of medication taking) and attend research visits every 3 weeks (i.e., weeks 3, 6, 9, 12) to complete additional assessments and receive compensation for doing so.

Quitting smoking is hard, and many Veterans struggle even with current treatments. This study is testing a safe, non-invasive brain stimulation called repetitive transcranial magnetic stimulation (rTMS), which is already FDA-approved to help people stop smoking. We're comparing two types—standard and personalized—to see which works better. We aim to find the best option to help Veterans quit for good.

This is a 28-week-long treatment study for people with Alcohol Use Disorder who want to stop or cut down their drinking. The purpose of this study is to determine whether an investigational medication, Mazdutide, affects craving for alcohol and/or alcohol drinking while taking the study drug. Participants will be randomly assigned to Mazdutide or a matched placebo
