Cocaine Use Disorder (CUD)

The investigators aim to examine the effect of transcranial focused ultrasound (tFUS) on brain activity and cocaine craving in adults with cocaine use disorder.

The goal of this clinical trial is to learn if Cobenfy influences the effects of cocaine in people with cocaine use disorder. This trial will also provide information about the safety and tolerability of combining Cobenfy and cocaine. Researchers will compare Cobenfy to a placebo (a look-alike substance that contains no drug) to see if Cobenfy is a safe, tolerable and effective at blocking cocaine's effects in participants with cocaine use disorder. Participants will: * Participate in an 11-day inpatient trial * Take Cobenfy or placebo twice per day. * Participate in experimental sessions to test the effects of Cobenfy (or placebo) on the response to cocaine and cocaine self-administration.

The study aims to address the neurobiological basis of cognitive impairments in chronic cocaine users by investigating the potential impact of an acute potassium channel blockade on working memory performance and other cognitive functions.

The purpose of this study is to evaluate the effects of Contingency Management (CM)+transcranial magnetic stimulation (TMS) on treatment outcomes in individuals who are initial non-responders and to evaluate the effects of CM+TMS on putative mechanisms of change

Substance misuse is one of the most common risk factors for health problems and premature death among adolescents and young adults worldwide. Although there are effective treatments for substance use disorder (SUD), there is still a need to further improve their effectiveness and make them easier to access. Early research suggests that substance-specific inhibition training, when used in addition to specialized treatment, can improve treatment outcomes. This training aims to strengthen inhibition specifically in situations with substance-related cues. The goal of this project is to offer this training for the first time in the form of a smartphone app, which is expected to increase the availability of the training. The main aim of the study is to evaluate whether this new app-based cognitive training is feasible as an add-on to the treatment of SUD in adolescents and young adults. In addition, the study will gather preliminary insights into whether the training affects drinking behavior and related brain processes. The project will be conducted as a double-blind, clinical pilot study. A total of 210 adolescents and young adults between 14 and 35 years old will be recruited from five specialized treatment centers. After the first study visit, participants will be randomly assigned to one of two groups: (1) an intervention group receiving the alcohol-specific inhibition training or (2) a control group receiving a similar alcohol-nonspecific inhibition training. During their participation, all participants will complete six short training sessions with the app. About one month later, they will complete six additional booster training sessions. This research may help develop effective, easily accessible tools to support young people with substance use disorder.
