Is using ethyl chloride for narcosis harmful?

Don't do it: This is a new high for young people, who spray it down their lungs. As a pathologist, i've autopsied several "huffing" deaths from people spraying stuff into their lungs, driving out the oxygen and/or freezing their airways fatally. Ethylene chloride's probably like the others. If u die this way, everybody will make fun of u and u'll miss many opportunities life has to offer. Cherish life, man.
