Ya as far as inhalants go whippets are by far the safest. I checked it out before I tried it for the first time, I dosnt kill brain cells as far as I no and the only real dangers are that if you dont get real air after you could die of lack of oxygen and that it gets rid of all the b-12 in your blood so its not sumthing to do many times. And I never felt anything from it. I took the can and shot it into a long bread bag and inhaled it and I got nothing from it.
