Don't be a friend. What do you need it for? Unless you plan on gas masking a bong in which case forget yeah dude
maybe a bit of using it as a bong
Ignoring my general dislike of drugs for a moment, that sounds like an incredibly good way to choke yourself out.
Why do so many of you obsess over gas masks? Is it a loveual thing or what?
Well they are very popular in BDSM play.
My dad gave me his old Gasmask from when he was in the Navy, it's so cool, sometimes i just browse the internet wearing it
