You'd have to be stupid to get your N20 out of a Pam can though.

Here's a secret: nitrous oxide is legal to recreationally consume in most of the 50 states and can be purchased at porn stores. Seriously, they keep it under the counter in whipping cream canister form and they will also sell the "cracker" needed to safely pierce the canisters as well as heavy duty balloons.

It's of course cheaper to get it online: http://www.creamright.com/WHIP-CH.html

Don't let the idiot who made this blog post turn your off. N20 is one of the safest medical drugs in existence. It's the anesthetic with the longest history of use and it is as safe as can be. The only danger is that you hold your breath too long, but that's not a big deal, just make sure you breathe some oxygen after a minute. Also, in high doses over a long period of time, N20 depletes your body's vitamin B which is very bad, but this is easily fixed by a multivitamin.
