Oral THC undergoes first-pass hepatic metabolism, converting delta-9-THC to 11-hydroxy-THC (11-OH-THC), which crosses the blood-brain barrier more readily and produces more intense, longer-lasting psychoactive effects. Onset is delayed 30-120 minutes (versus 5-10 minutes for inhalation), and the slow absorption curve means peak effects may not occur for 2-4 hours. This delayed onset is the primary driver of overconsumption incidents: consumers who feel no effect after 30 minutes take additional doses, resulting in emergency department presentations for acute cannabis toxicity — paranoia, tachycardia, panic attacks, and psychotic episodes. Pediatric exposures have surged in legalized states: Colorado reported a 1,375% increase in cannabis-related pediatric ED visits from 2009-2015, largely driven by edibles in child-attractive packaging (gummies, candies, cookies). Dosing accuracy remains problematic — FDA and state testing labs have documented THC content varying 50-200% from labeled dose, with uneven distribution within multi-dose packages (hot spots).","synthesis":{"derived_risk_level":"moderate_to_high","synthesis_confidence":0.5,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":1,"vulnerability_escalated":true,"escalation_reason":"Child exposure group","compounds_resolved":1,"compounds_total":1,"synthesis_date":"2026-05-09","synthesis_version":"1.2.0","methodology_note":"exposure_modifier and adjusted_magnitude are computed from ALETHEIA-calibrated heuristics (route × duration × frequency multipliers, clamped to [0.5, 1.4]).
