nitrous oxide or N2O, is a gas used to put people to sleep for various surguries, increase the compression in an engine to make a car go faster, in the production of whipped cream and for recreational purposes.

any thing richer than 80% nitrous that is inhaled will cause blacking out, and possible brain cell asphyxiation if exposure is prolonged. inhalation of a more oxygen rich mixture can still produce an intoxicating effect, but without damaging the brain or body in any way.

nitrous sends you flying to other planets in a differnt dimension made of nothing. your senses are left behind as you fly through the unconcious and return to the insane soap opera absurdness that is modern life.

nitrous oxide, a short acting disassociative anesthetic found in propellants for food products, such as whipits.

Commonly used in dental surgery, not unlike pharmocologically to pcp dxm or ketamine ect, though chemically and experintially unrelated.

In the automotive world, is short for nitrous oxide, a chemical compound used to increase vehicle engine performance. Also referred to as nos or noss in certain circles, though overall this reference is looked down upon.

Next to Special K this is the lamest 'drug' out there... it lasts for what half a minute.
Some fucktard tried picking a fight with me while 'high' on balloons, the dummie didn't have the sense to know that I was around 50lbs bigger than the person and could have easily knocked them out on a whim.

1. The official IUPAC name for nitrous oxide, N2O, is dinitrogen oxide. Like many substances, N2O has a common name, ‘nitrous oxide’ which is so widely used that most people refer to the gas by its common name. The gas was discovered by Joseph Priestley.

2. The gas used by most dentists as an anaestetic. The mixture of N2O to Oxygen is often about 50/50 (O / N2O), you need atleast 20/80 (O / N2O) in order to remain concious. This is not a concern when inhaling for recreation using a whipper.

3. An substance that when used properly, will cause a deeply satisfying detachment from the physical world and person. An interesting thing about N2O is that it Does Not harm your body in anyway aside from gradual B12 deficiency, which can be combated with a over the counter B12 supplemnent every week, making this probably the safest intoxicat-or available. The best way for inhaling Nitrous is through the use of a Half-Pint whipper from iSi off Amazon.

You may also obtain canisters, also known as 'whippets' from Amazon. iSi brand whippets are the best, Liss being the second. If amazon is out of the question you can also pick it up at the local Market or Restaurant supply store, just make sure you DO NOT ask for 'Nitrous,' ask for N2O chargers-- clerks get uppity sometimes when you ask for it by its common name. One canister will cause about the same effects as at the dentist. Atleast two straight whippets generally must be used to send you into a dreamstate. In said dreamstate time will pass incrediably fast, with detached logic and thought. When you come down from the high it will be realised that only 5 minutes have infact passed. Three canisters are enough to cause you too pass out for roughly a minute, this is almost always filled with very amusing and interesting dreams.

*Important* If inhaling Nitrous for recreation it is Very important not to do these, people Have died from these obviously illogical things:

1. Try to inhale N20 directly from whippits, or point escaping gas at anyone. The gas WILL give you frost burn.

2. Strap a gas mask to your face. If you pass out, you want your body to get oxygen.

3. Lock yourself in a room, closet, car, or refrigerator with a tank of nitrous and open it.

4. Stand up and do it. Stay away from open windows.

5. Use a large tank without a regulator or which isn't strapped down.

6. Use homemade nitrous. Unless you are a chemist, you're likely to get a load of rubbish like NO2, H2NO3, and other yummy toxic things.

7. Allow yourself to lose sight of moderation. No one likes a Nitrous Whore.
