Why will air duster kill you?

Air duster, commonly used for cleaning electronics, contains compressed gases that can be inhaled for a brief euphoric effect, but this is extremely dangerous. Inhaling the propellant can lead to asphyxiation, cardiac arrest, or sudden death due to heart arrhythmias. Additionally, the chemicals can cause severe damage to the brain and other organs, leading to long-term health complications. Misuse of air duster is life-threatening and should be avoided.
