Cannabis Intoxication Mechanism
Cannabis Intoxication Mechanism
Cannabis intoxication occurs via activation of the Cannabinoid Receptor 1 (CBI receptor).
CBI Receptor Agonist
CBI Receptor Agonist
A substance that activates the CBI receptor, producing cannabis-like effects.
Symptoms of Cannabis Intoxication
Symptoms of Cannabis Intoxication
Effects include euphoria, anxiety, paranoid delusions, slowed time perception, impaired judgment, social withdrawal, increased appetite, dry mouth, bloodshot eyes, and hallucinations.

Study Notes
Intoxication Mechanisms and Treatment
- Cannabis intoxication: CBI receptor agonist; causes euphoria, anxiety, paranoid delusions, slowed time perception, impaired judgment, social withdrawal, increased appetite, dry mouth, and conjunctival injection.
Patient Presentation and Diagnosis
-
48-year-old female: Brought to ED by son at 9:00 AM, extremely happy but confused and disoriented; slow speech, delayed responses, poor coordination, difficulty balancing; dry mouth, extreme hunger, minimal breakfast; bloodshot, congested eyes; good hydration, adequate respiratory and cardiac function.
-
Patient's relative: Nervous and avoidant.
Diagnostic Considerations
- Mechanism of Action: The clinical presentation suggests cannabis intoxication.
Appropriate Management
- Treatment: Symptomatic treatment for intoxication.
- Withdrawal: Psychosocial support, and interventions for potential withdrawal.
Additional Patient Examples
-
22-year-old female: Brought to ER by friends; confused, disoriented, unusual sensory perceptions (sounds, colors); talks to self, moves anxiously, erratic mood changes, reports being chased. Dilated pupils, sweating
- Possible diagnosis: LSD intoxication. (visual hallucinations, auditory hallucinations, depersonalization, paranoia, anxiety)
-
24-year-old male: Wound to index finger; history of intravenous drug use, heavy alcohol consumption.
- Possible diagnosis: Alcohol withdrawal with delirium tremens. (Possible delirium, sympathetic overstimulation, and altered mental state).
-
Important Considerations:
-
Individual history and presentation matter in diagnosis: Specific symptoms help pinpoint cause.
-
Withdrawal symptoms, and their severity are tied to substance use: Assess for both current intoxication and the potential for withdrawal.
