What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 160 participants in total. It began in 2025-10-28 with a primary completion date of 2030-02-28.

Brief Summary

Dysregulation in stress responsivity is a growing psychiatry-transdiagnostic fundamental phenomenon, with limited therapeutic strategies. With the legalization of medical and recreational cannabis, many people consume cannabidiol (CBD; a nonintoxicating cannabinoid) to alleviate stress response, without the benefit of scientific guidance. To address this gap, the investigators propose a rigorous translational neuroscience study in a clinical high-risk population to define the roles of CBD in stress response with mechanisms of mesocorticolimbic-network function and hierarchy, neurometabolic, endocrine, and behavior, building upon convergent evidence from animal models and human evidence from our laboratories.

Eligibility Criteria

Inclusion Criteria: * Ability to understand and give informed consent. * Individuals between 18 and 25 years old; Sex is used a biological factor (50% of individuals recruited will be females, allowing sex comparisons). * English speakers. * Cognitive performance at threshold of greater than or equal to 23 as assessed by the Montreal Cognitive Assessment (MoCA). * Presence of ELA at threshold of at least one type of maltreatment measured by the Maltreatment and Abuse Chronology of Exposure (MACE) Scale and/or one type of maltreatment scored moderate/severe as measured by the Childhood Trauma Questionnaire (CTQ) * Presence of moderate/heightened stress as measured with a score of greater than or equal to 14 on the Perceived Stress Scale and/or high trait anxiety at threshold score of greater than or equal to 40 as measured with the State-Trait Anxiety Inventory (STAI) and no greater than moderate anxiety scores (max. 14) as measured by the Generalized Anxiety Disorder-7 (GAD7) Exclusion Criteria: * Have a medical condition that would make study participation unsafe, and/or which would make treatment compliance difficult, and/or would prevent adherence to study procedure. This includes but is not limited to the following criteria: history of cardiac disease, arrhythmias, neurological disease of central origin, head trauma, and seizures. * Meet criteria for any current psychiatric diagnosis as per DSM-5 \[determined with the Mini International Neuropsychiatric Interview for DSM-5 (M.I.N.I. version 7.2)\]. * Using any psychoactive drug (other than nicotine and/or alcohol) in the past seven days (determined by lack of acute withdrawal symptoms, the negative result of a urine drug screen, timeline follow back, and alcohol breathalyzer to detect alcohol intoxication). * Positive urine drug screen (tetrahydrocannabinol, cocaine, opiates, benzodiazepines, barbiturates, amphetamines, morphine, methadone, methamphetamines, oxycodone, phencyclidine, tricyclic antidepressant, buprenorphine, methylenedioxymethamphetamine) * Use of cannabis products, including CBD, during the past three weeks (determined with urine screen and self-report). Urine drug screen will be performed at each encounter. (Note: Epidiolex is known to sometimes cause a false positive for THC on urine toxicology; drug screen in visit after first CBD administration will not include THC as not to diminish the study blind. Stored urine will be tested for THC after study blind is opened). * Use of medication altering BOLD response, neurometabolic/glutamatergic levels, and endocrine function, including psychotropic medications (e.g., SSRIs), during the past three months. * Participation in non-medication-based treatments for anxiety or heightened stress, including cognitive behavioral therapy or other evidence-based treatments, in the past three months. * Medical or psychiatric contraindications for CBD administration (e.g., history of hypersensitivity to cannabinoids) or any of the ingredients in the product (sesame oil). * Being pregnant or breastfeeding. * Not using an appropriate method of contraception such as hormonal contraception (oral hormonal contraceptives, Depo-Provera, Nuva-Ring), intrauterine device (IUD), sterilization, or double barrier method (combination of any two barrier methods used simultaneously, i.e., condom, spermicide, diaphragm). * Participating in another pharmacotherapeutic trial in the past three months. * History of impaired renal function or elevated liver enzymes at prescreening. The exclusionary lab values are: 3x normal AST/ALT, 1.5x bilirubin or \<30mL/min/1.73m2 eGFR, or QTc\>500. * Participants who have used any medication, dietary supplements (and/or grapefruit juice), or combination of medications and supplements known to alter the metabolism of, or interact with CBD (bupropion, rifampin, barbiturates, phenothiazines, cimetidine, etc.) 14 days prior to and during the duration of the study. * Any condition that would make study participation unsafe and/or which would prevent adherence to study procedure (e.g., suicidal or homicidal ideation requiring immediate attention, severe inadequately treated mental health condition) as determined by the study clinician and/or PI.
