Evaluate PK Profile

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
