Abstract: 
Despite expanding acceptance of cannabis for medicinal use, empirical literature remains sparse regarding the long-term mental and neurobiological outcomes of continuous cannabis exposure over several decades. This self-case study examines the psychobiological trajectory of a biomolecular psychologist who has used cannabis intermittently since the 1970s and therapeutically since 2010 to manage polypharmacy withdrawal, opioid dependence, and psychiatric symptoms. The analysis integrates self-observational data, neurocognitive assessments, pharmacological history, and psychosocial context to evaluate outcomes on affect regulation, cognitive performance, neuroplasticity, and motivation. The case challenges persistent assumptions of irreversible cannabis-induced cognitive decline and supports the hypothesis that sustained cannabinoid modulation may promote neural resilience when employed within a biomolecularly informed framework. Findings are illustrative and intended to generate testable hypotheses rather than establish causality.
