One thing I want to point out is that ether doesn't just make you pass out by a little sniff. They have to hold it to your face for a while for it to take effect. So these people must have a lot of balls to do this out in the open like that. Trust me I work with diesel machines all the time and have s gotten a snout full of ether, It might make you loopy for a while but it doesn't make you pass out with one sniff.
Not saying I don't believe what is being said just saying it takes a lot for it to do its work. Thanks for the info street.
