I carry some of them small containers of the stuff in case I have a puncture and need to blow up the tyre on the trail. Does this ban mean we won’t be able to get them anymore.

That is CO2 not N2O.

Oops sorry I thought it was those little containers that the kids were using to get high on. Good job I am not a drug dealer.

I've never owned co2 canisters . Always mean to get some. Never do ..call me old skool I usually carry a pump . When i started reading this . The little angel on my shoulder is like " quick by some cannisters.

CO2 is toxic to humans, good job you weren't peddling that stuff because you'd likely also be done for murder! It's why we exhale the stuff in our breath...Oops sorry I thought it was those little containers that the kids were using to get high on. Good job I am not a drug dealer.

CO2 is not toxic, it is part of the atmosphere at 0.04% (and rising), but it is not actually toxic, as in poisonous. At high levels (above 100x normal) it will suffocate you. That is also the level of CO2 in our breath that we exhale. But our breath will not suffocate someone else because it has 16.4% oxygen, not the 21% that went in. So there is enough to live on, which is why mouth to mouth resuscitation works.
I worry you've said that too many times in life..
"No honey, I was just resuscitating her ...."

So everybody knows that by inhaling from a helium balloon, you can make your voice high pitched...
But one time, our college Physics professor wanted to show us that, CO2, being denser than air, would give the opposite affect... a deep voice.
Well, he inhaled just a bit too much and passed out. He decided after that to take that demonstration out of his program.

This reminded me to put a nitros oxide button on my handlebar .
CO is toxic, well it bonds permanently in your lungs making it impossible to breathe.
CO2 is also toxic if it starts building up in the blood. As Steve states, too much will asphyxiate you but raised levels are toxic and cause various issues. BTW, O2 has silimilar toxicity in raised levels. Fortunately our atmosphere has them in quantities we can manage. Or put another way, life on our planet has evolved to cope with the atmosphere it was granted!

My experience has been that CO2 tends to leak out of inner tubes faster than normal air. I know that when I've filled one with a cartridge, it is really down on pressure the next day much moreso than If I'd used a regular pump.

I agree that CO (carbon monoxide) is toxic, it binds to your red blood cells and you suffocate slowly as your blood cannot transport oxygen.
CO2 (carbon dioxide) is a different gas and although too much of it will kill you, it is not actually poisonous (at normal temperature and pressure).
I had to say that because someone correctly pointed out that O2 (oxygen) is poisonous under the correct circumstances. For example, pure oxygen is poisonous at higher pressure, as WW2 frogmen discovered when they dived too deeply with their O2 breathing apparatus. Below 32 feet depth if I recall correctly.

Instructions unclear, penis stuck in CO2 inflation canister. Am I doing it wrong?
I've had CO2 on my motorcycles and MTBs for decades, they can really pay off. But they are limited to what you can carry, as opposed to a pump which is unlimited. When I take the adventure motorcycle out in the boonies, I carry both CO2 and a tiny electric pump, because I could find myself WAY out there. For the MTB I mostly carry CO2, unless I'm going far out alone, then I have the manual pump too.
"CO2 is considered to be minimally toxic by inhalation. The primary health effects caused by CO2 are the result of its behavior as a simple asphyxiant. A simple asphyxiant is a gas which reduces or displaces the normal oxygen in breathing air. Symptoms of mild CO2 exposure may include headache and drowsiness."

CO2 can suffocate you at higher concentrations by displacing O2, but N2 can do that too (e.g. confined spaces). That is an unusual situation compared to every breath you take and the chemistry involved. It is especially relevant to cyclists.
Breathing is more than just getting O2 to your muscles, it helps remove CO2 from the blood. It’s important because of equilibrium reactions in the blood. CO2 reacts with water in the blood to form carbonic acid (H2CO3) and hydronium (H3O+), which acts as a buffer with bicarbonate (HCO3-) to maintain proper pH in the blood. Another equilibrium reaction between hydronium and O2 affects the release of O2 from hemoglobin into the muscles. Another important reaction in the blood involves lactate. Strenuous exercise generates lactic acid which lowers the pH in the blood. This is why Roglic and van Aert are using a "baking soda" supplement as a performance enhancer.

More generally (and off topic) - at the levels we have around the globe, CO2 is an entirely beneficial and indeed an essential gas - plants need it to grow, they expel oxygen in turn as part of the photosynthesis cycle. The idea of “reducing atmospheric carbon levels” is plain nuts, and unachievable anyway. Just ask Murray!

Found the climate skeptic using the weak plant food argument and promoting the disgraced Dr. Salby who resigned form his tenured positioned at UC Boulder after being investigated by the NSF. Salby was then fired from Macquarie University for being a generally shitty professor, and not, "His views on climate science".
He did do some notable work on ozone depletion though. Fortunately, like a lot of old white guys, he is dead now.

I found the video absolutely fascinating. Has anyone disproved his science, rather than just disagreed with his conclusions? People can get sacked from their jobs for all sorts of reasons, especially when they disagree with the accepted view. They don't have to be "an old white guy", they can be anyone. Apart from Marie Curie, Florence Nightingale and many other women (also old, white and dead) the vast majority of good (still revered today) science was done by old (mostly, but not exclusively) white guys, now sadly all dead.

Ad hominem attacks are usually seen as a weak response by those wishing to divert attention away from the veracity of ‘the message’. Fortunately, they tend to be seen for what they are.
Anyway, let’s laugh our way back to Nitrous oxide, lol!

Yes but your boy Murry Salby there was actually disgraced in real life & therefore that is nothing like an ad hom attack as much as you would like to imply.
Salby was notorious for fiddling expenses, failing to turn up for teaching gigs and pinching gear from his employers, so if you're here as a climate change denier then you should really choose a more credible cheerleader lest people with the wherewithal to check these things show you up a bit eh?
And after all is said and done, you'll find this is a mountain biking site where this schtick self destructs before long. Nice knowing you.

As an almost old white guy who has taught geology and environmental science at the college/university level for several years I could easily dispute the veracity of Salby's message (propaganda), but it is beyond the scope of this forum. I would much rather talk about bikes to be honest.
I agree, let's get back to the nitrous, a potent greenhouse gas (~300 GWP). Damn, I said I was not going to talk about that. Fun fact, you can modify a CO2 inflator to open whippets by inserting a spacer from a hub axle to make up the difference in cartridge height.

At least we can all agree on one thing. It would be completely stupid to think that humans are not at least 1% responsible for climate change, but also to think they are 100% responsible. It's equally outright stupid to think we can fully predict the unintended consequences of doing anything major to change it. The people calling for fast action on some things simply can't see the potential damage of quick changes.

Nobody is seriously suggesting that the climate does not change, that is self evident. It always has.
Nor am I here as what you term a ‘climate denier’. Believe what you want.
I’d respectfully suggest that it’s just not as clear cut it is being presented. A little from history:

There is not one single person on the planet who actually knows the level of the problem, how much is anthropogenic, and what will happen if we try to mess with nature. Even the anthropogenic problem.
