Official title
Acute Dose-Dependent Effects of Oral THC on Physiological and Subjective Responses in Healthy Cannabis-Experienced Adults
Overview
The goal of this clinical trial is to learn how a investigational medicinal product (THC) affects psychological and physical responses in healthy adults with prior cannabis use experience. The main questions it aims to answer are: \- How do different dose levels of the investigational medicinal product (THC) influence short-term subjective and physiological responses? Researchers will compare three dose levels of the study drug to a placebo (a look-alike substance with no active ingredient) to see how responses vary across sessions. Participants will: * Attend four in-person study visits, each involving a single dose of either the study drug or placebo * Complete questionnaires about their moment-to-moment experiences * Have their heart rate, blood pressure, and other physical measures monitored * Undergo serial blood sampling to measure circulating biomarkers
Interventions
- Drug AVCN319301b (6mg)
AVCN319301b is a standardized oral capsule containing a precise dose of Δ9-THC. - Drug AVCN319301b (9mg)
AVCN319301b is a standardized oral capsule containing a precise dose of Δ9-THC. - Drug AVCN319301b (15mg)
AVCN319301b is a standardized oral capsule containing a precise dose of Δ9-THC. - Drug Placebo
The matched placebo is an oral capsule identical in appearance to the active study drug and contains the same non-medicinal ingredients but no Δ9-THC. It is manufactured to match the active capsules in size, color, taste, and packaging to maintain blinding for participants and study staff.
Primary outcome measures
- State Trait Anxiety Inventory - State [Time frame: Baseline and multiple points up to 300 minutes post-dose.]
Secondary outcome measures (11)
- Subjective Drug Effects (Drug Effects Questionnaire; DEQ) [Time frame: Baseline and multiple points up to 300 minutes post-dose.]
- Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] [Time frame: Adverse event recording begins with receiving the first dose of investigational medicinal product and ends one week following the last dose of investigational medicinal product (end of study).]
- Mood States (Profile of Mood States; POMS) [Time frame: Baseline and multiple points up to 300 minutes post-dose.]
- Positive and Negative Affect (PANAS-SF) [Time frame: Baseline and multiple points up to 300 minutes post-dose.]
- Heart Rate [Time frame: Continuous measurements from baseline to 300 minutes post-dose.]
- Heart Rate Variability [Time frame: Continuous measurements from baseline to 300 minutes post-dose.]
- Blood Pressure [Time frame: Continuous measurements from baseline to 300 minutes post-dose.]
- Cortisol Levels [Time frame: Blood samples collected at multiple points from baseline to 300 minutes post-dose.]
- Endocannabinoid Levels [Time frame: Blood samples collected at multiple points from baseline to 300 minutes post-dose.]
- Cmax of Δ9-THC and its Metabolites [Time frame: Blood samples collected at multiple points from baseline to 300 minutes post-dose.]
- Tmax of Δ9-THC and its Metabolites [Time frame: Blood samples collected at multiple points from baseline to 300 minutes post-dose.]
