Body & Organ Damage

Alcohol metabolism produces acetaldehyde — a highly toxic compound that causes widespread organ failure. Cannabinoids do not cause cellular necrosis or organ tissue death when used within standard thresholds.

Alcohol's Toll

  • •Liver: Fatty liver → alcoholic hepatitis → cirrhosis. 75.6% of all alcohol-specific deaths are from liver disease. The liver has no pain receptors — you can destroy 70% before feeling symptoms.
  • •Heart: Cardiomyopathy (weakened heart muscle), hypertension, arrhythmias, increased stroke risk.
  • •Pancreas: Chronic pancreatitis — irreversible inflammation and tissue damage.
  • •Cancer: WHO Group 1 carcinogen. Directly causes 7 types of cancer: breast, liver, colorectal, esophageal, mouth, throat, and larynx. 3.3% of all UK cancer cases (~11,900/year).
  • •Immune system: Suppresses immune function, increases susceptibility to infections and pneumonia.
  • •Gut: Erodes gastrointestinal lining, causes malabsorption of nutrients, increases risk of GI bleeding.

Cannabis's Minimal Impact

  • •Liver: No hepatotoxicity. Cannabinoids do not cause liver tissue damage or failure.
  • •Heart: Minor transient cardiovascular stress during acute use (increased heart rate 20-50%). No baseline risk elevation long-term.
  • •Cancer: Not classified as a carcinogen. No epidemiological link to lung cancer when controlled for tobacco.
  • •Lungs (smoking): Combustion smoke contains tar and irritants — causes chronic bronchitis. This is entirely avoidable by vaping or using edibles/oils.
  • •Lungs (vaping/edibles): Zero respiratory risk. Edibles bypass the lungs entirely — processed by the liver into 11-hydroxy-THC.
  • •CHS: Rare condition (Cannabinoid Hyperemesis Syndrome) — cyclical vomiting from over-saturation of gut CB receptors.

The Margin of Exposure (MOE)

Toxicologists use the MOE index to measure the ratio between a substance's lethal dose and typical human intake.

< 10
Alcohol MOE — "High Risk" category. Only 10x a standard dose can be fatal.
> 10,000
Cannabis MOE — demonstrating an exceptionally vast safety margin.
