Is it bad if I kick my friend out of my house because he threw up while we were high?
Why did he throw up?
I dunno! We were just smoking and eating and all of a sudden he puked everywhere.
I understand being upset that someone threw up in your house, but it doesn't sound like it was malicious on your friend's part. Sometimes people have a bad reaction when doing drugs. Instead of kicking him out, you should consider getting him help for his drug use.
We aren't drug addicts. We were just smoking pot which is legal here.
That's good that you weren't using hard drugs! It certainly seems like your friend just had an unexpected reaction or may have actually gotten the stomach flu. I don't think you should kick them out for accidentally throwing up in your home.
