Shooting heroin and inhaling nitrous oxide?

I'm wondering if anyone has ever tried shooting smack and immediately after the injection when feeling the rush inhale nitrous oxide? Would there be any negative side effects or dangers in doing this? Thanks for any info or advice.

 

I wouldnt think there would be too much to worry about but watch your breathing. Heroin makes you breathe more slowly then when you hit the nitrous you forget to take in oxygen so go easy and BREATHE. As long as your h dose isnt too high i think youll be straight. My question is why would anyone want to mix those two substances? That would be a really weird combo.
Report back with your findings nitrous aint gonna kill you.

 

just dont put anything on your face while you do it. in case you pass out. so you dont choke

 

sounds gay

 

I did it with dilaudid once and it was the greatest rush of my life. Sound like a really weird combo but it meshes really well. I cant really describe it but WOW
