Filter by:Alcohol and cannabis are the most misused psychoactive substances in the United States, and their misuse among African American young adults has the potential to be especially problematic. The proposed research examines how daily and racial stressors (e.g., racism and discrimination) may lead to alcohol and cannabis use among African American young adults, and what individual and community coping and resources mitigate this causal effect. This research is designed to identify possible targets for culturally responsive prevention and treatment efforts to help prevent and reduce alcohol and cannabis use among African American young adults.
This is a randomized, parallel-group study designed to explore the differences between cannabis intoxication, alcohol intoxication and co-intoxication involving both alcohol and cannabis, utilizing electroencephalography (EEG) as well as more traditional intoxication measures such as breath alcohol concentration and balance metrics. If eligible for the study, participants will be randomized to complete one study session in our mobile laboratory, during which they will use either alcohol, cannabis (which will be self-administered, ad libitum) or both alcohol and cannabis.
Researchers at the University of Colorado Anschutz Medical Campus, Colorado School of Public Health, and Injury & Violence Prevention Center want to learn more about how people are affected by cannabis in different ways. We will use a driving simulator to compare the driving performance of adults who use cannabis daily, occasionally or have not recently used cannabis.
Though regulated cannabis sales are increasing, little is known about the individual health effects of cannabis regulation. Data from countries with a regulated market can be used to test the effect of regulation on the price of cannabis in the illicit market, and to explore its effect on social and health outcomes at the societal level, but strength of evidence for individual health and social outcomes is more limited because it must be aggregated on a state or country level. Data on individual and social outcomes should include baseline measurements before and outcome measurements after regulations changed. In this context, randomized-controlled trials are the least biased source of data on the effects of interventions. The SCRIPT study aims to investigate the individual health and social impact on recreational cannabis users who are allowed to purchase authorized, regulated cannabis from Swiss pharmacies compared to users who buy cannabis on the illicit market. Participants are randomly allocated in one of the two groups and followed-up for 6 months. After 6 months, all participants are allowed to participate in the intervention and the cohort is followed up for another 18 months. The intervention includes various offers: Participants can choose between cannabis sorts and delivery methods, and they are encouraged to shift from smoking cannabis to vaping cannabis-containing e-liquids, vaporizing cannabis blossoms or using oral cannabis. Vaping / vaporizing electronic devices are also recommended. At the same time, pharmacists offer opportunistic smoking cessation and problematic cannabis, alcohol use and further drug use counseling that conforms to motivational interviewing principles. The SCRIPT study adheres to rigorous quality criteria for the production and storage of regulated cannabis products. Only vaping / vaporizing electronic devices which are validated to reduce exposure to toxicants compared to cannabis smoking are recommended.
The goal of this study is to learn about the effects of combining alcohol with cannabis concentrate products which contain high levels of THC. The main question[s] it aims to answer are, 1) How does the order in which someone consumes THC and alcohol in a given co-use session impact outcomes such as blood alcohol level, heart rate or subjective drug effects, and 2) how does THC percentage in cannabis influence outcomes following alcohol and cannabis co-administration. Participants will be scheduled for our mobile lab to come to their residence. During the session, they will: - consume a standardized dose of alcohol as well as use their own preferred cannabis concentrate product. - they will then remain in our mobile lab for about 4 hours and complete some surveys as well as do some cognitive tasks on an iPad every 30 minutes. - They will also have their blood drawn three times throughout the session, and will periodically be asked to blood into a breathalyzer to measure blood alcohol level. Researchers will compare people who use alcohol prior to cannabis to those who use cannabis prior to alcohol to determine whether order of use impacts outcomes.
The goal of this treatment development project is to develop an adaptive ecological momentary intervention (a-EMI) for young adults using marijuana and alcohol that is grounded in self-regulation and social cognitive theories. To determine the most efficacious intervention strategies, the investigators will test variations of intervention components to identify the best combination. The study will take place at the Center for Integrated Health Care Research at Kaiser Permanente Hawaii (KPHI), located in Honolulu (island of Oahu). Following pilot testing with 6 participants, the study team will assess the feasibility and efficacy of intervention components on two primary outcomes (negative consequences and protective behavioral strategies [PBS]) using a fractional factorial experimental design, with post-intervention assessment and one- and three-month follow-ups. 136 diverse young adults recruited from KPHI who report current simultaneous alcohol and marijuana (SAM) use will be randomly assigned to one of eight groups, representing experimental conditions that include or do not include intervention strategies focused on craving reduction and PBS. As a result of this process, individual and/or combined components that lead to improved outcomes will be retained in a subsequent randomized controlled trial, while ineffective components will be eliminated.
The study is about helping teens who are involved in the court system to cut down or quit using marijuana. Teens may be asked to test out an experimental smartphone app, called TECH, that will be used only by teens in this study. This app is a private online community where teens can work towards changing their substance use and other behavior with the help of other anonymous teens. We will use this information to learn how the app may help teens make a change and to improve the TECH app.
The use of Cannabis is increasing in the population, and the effects that this might have on different medical procedures are poorly understood. Particularly when submitted to deep sedation or general anesthesia, there is no consensus on best drugs or doses to deliver. The purpose of this clinical trial is to clarify the influence of chronic cannabis use during office based general anesthesia for extraction of teeth. The procedures will be performed in the Oral and Maxillofacial Surgery Clinic at the College of Dentistry.
This study consists in the the design, implementation, and evaluation of the first web-based computer tailored intervention program aimed at the prevention of cannabis use in Spanish adolescents (ALERTA CANNABIS). A Cluster Randomized Controlled Trial is conducted to test the effectiveness of ALERTA CANNABIS in students aged 14 to 18 years across 34 high schools from Andalusia (southern Spain), which are randomized either to the experimental or the control condition (EC and CC).
This research project proposes a novel approach to elucidate the biological adaptations associated with heavy cannabis use and to assess whether such adaptations are predictive of higher cannabis craving in response to both cannabis cues and stressors.
