Background: People who will participate in research studies need to undergo proper screening, evaluation, and assessment (SEA). SEA helps keep those who participate in studies safe. It also helps ensure accurate study results. The National Institute on Drug Abuse (NIDA) Intramural Research Program (IRP) wants to screen people with alcohol and/or substance use disorders (ASUD) as well as people without ASUD for ongoing studies at NIDA in Baltimore, MD Objective: To screen people with or without ASUD for ongoing studies at NIDA. The ultimate goals are to learn why some people (1) use drugs; (2) stop using drugs; (3) use drugs but do not get addicted; and (4) never use drugs snd to develop ASUD treatments. Eligibility: People aged 18 years and older. They may (1) currently use nicotine, alcohol, opioids, cocaine, or other drugs; (2) no longer use them; or (3) have never used them. Design: Participants will have 1 screening visit that could last up to 8 hours. The visit may be split over more than 1 day. The duration of the screening may vary for each individual based on which studies they are interested in and screened for. The tests they undergo may vary and may include the following: * Physical exam. * Blood, saliva, and urine tests. * Breath samples that test for alcohol and carbon monoxide. * Test of heart function. * Smell test that measures sense of smell. * Tests of memory, attention, and thinking. * Mental health evaluation. * Mock magnetic resonance imaging (MRI) scan. * Questionnaires about alcohol and other drug use, mental health, medical history, and life in general.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
