Freon Inhalation: Health Risks, Symptoms, and Toxicity

Freon (chlorofluorocarbon/hydrofluorocarbon refrigerants) is a dangerous inhalant. Intentional inhalation ("huffing") for euphoria causes severe toxicity.

Acute Effects

• Dizziness, lightheadedness, headache
• Nausea, vomiting
• Unconsciousness, asphyxiation (displaces oxygen)
• Cardiac arrhythmias (sensitizes myocardium to adrenaline)

Chronic/Organ Damage

• Heart, liver, kidney, brain damage
• Neurological deficits, cognitive impairment
• Potential fatal "sudden sniffing death" syndrome

Critical Warning

Freon inhalation is life-threatening. It is not a safe recreational substance. If someone has inhaled refrigerants, call emergency services immediately. Treatment is supportive; no specific antidote exists.
