IF smoke acts s a flammble gas then why is it safe to fill our houses full of smoke when we get high?

Doing that would be a bad idea...
Smoke is just unburned particles of fuel...they're unburned because of a lack of oxygen when you burn the pot. Adding pure oxygen into the mix could cause the smoke to spontaneously combust, possibly inside the lungs of whoever decided to try it.
If you want to use a blast of air, you would at the least have to mix the O2 with nitrogen in a ratio of less than 20/80 (O2/N2).
First off, smoke is not a gas. And I think you're not understanding the role that o2 plays in flames. Oxygen itself is not combustible, but when added with something that is, even in the slightest, the combustibility will be magnified by a helluva lot.
Just like I think you missed my point when I was talking about oxy-acetylene torches. WITHOUT oxygen the torch really doesnt get that hot, but when o2 is added to the flame it becomes extremely hot.
From Wikipedia:
Quote:
Combustion hazard
Highly concentrated sources of oxygen promote rapid combustion and therefore are fire and explosion hazards in the presence of fuels. Oxygen itself is not the fuel, but as a reactant, concentrated oxygen may allow combustion to proceed dangerously rapidly. The fire that killed the Apollo 1 crew on a test launchpad spread so rapidly because the capsule was pressurized with pure oxygen as would be usual in an actual flight, but to maintain positive pressure in the capsule, this was at slightly more than atmospheric pressure instead of the ⅓ normal pressure that would be used in flight. (See partial pressure.)
Hazards also apply to compounds of oxygen with a high oxidative potential, such as high concentration peroxides, chlorates, perchlorates, and dichromates; they also can often cause chemical burns.
It doesnt really seem as if we're going to dissuade you. So just be careful is all I can really say.

There's no reinforcing in that wall. Plus it takes 28 days for the mortar in a CMU wall to reach compressive strength according to ASTM standards. That wall was completed a day or so before.
Just tell us the velocity and how many pounds per sq/in.
That's what's aggravating about myth busters. They go through the scientific method, but exploit weaknesses in the control. Granted raw data isn't as entertaining.

I will fill a balloon with pot smoke and then mix it with oxygen and then hold it over a flame with a long stick
Are you telling me that this experiment is not relevant for some reason?
I don't intend on trying this again and i have only done it once or twice until i began to question its safety. Thank you guys for the feedback and even if it is not so dangerous that i didn't blow up the first or second time, i guess that doesn't mean it is completely safe or worth the risk. This is the feedback i was looking for.
So what about the cancer treatment and why would 100% oxygen be bad to breath for long periods of time, or is it? Do we need Nitrogen and do our bodies obtain the majority of it from the air?

I think the POINT was made... It should be eye opening from a safety standpoint, even without raw data!

I didn't say i doubted it, i just want to see it done. It makes me more believable to another person if i say truthfully i have seen the results with my own eyes.
If you just believed everything you ever read and never experimented yourself then you would be very gullible person. Science books revised for reasons. New discoveries come from people who question what is currently believed and experiment to see if the same results are obtained. I have always been told 'you are not a scientist until your experiment can be recreated by someone else and they obtain the same exact results as were obtained in the original experiment.'

There was this one story about a gas plant producing oxygen as a by-product, so they had the liquid oxygen pour out a tube onto a bed of rocks out back of the plant.
liquid oxygen boils -280F and freezes at -370F, it must have been something other than liquid oxygen.

What about butane? It boils at -0.5C which is about the same temp that water freezes. However i can fill a beaker full with 500ml of butane and observe it in it's liquid state for quite a while before it boils and dissipates into the air. It is definitely boiling, or evaporating if there is a difference and i am sure there is(i just don't know). I know that the boiling point is very very different between oxygen and butane, but is it so different that we could not possibly see Oxygen in its liquid state in a unpressurized environment?

Oooooopsies... lol well disregard that one post.

So i still need some balloons. Can anyone help improve my experiment? Would the smoke need to be as fresh as possible is one question i have for myself?

If you want to blast the smoke out of your bong, just use a fucking air compressor.
You breathe air anyhow, but breathing out of a welding-grade oxygen tank would be a good way to get chemical pneumonia.

What he said ^
And if you were also thinking that the added oxygen high would add to the experience, which it probably would, at the same time I think it would decrease your mj high because all that oxygen is taking up your red blood cells that I'm assuming distribute the THC as well.
If you were going to try blowing any oxygen at all through a bong, which I would NOT recommend, I would suggest making your own whole new bong complete with extra valves or seals or whatever just for oxygen tubes, and maybe make the whole thing a closed system. If your going to do something, do it right is what I always say.
Just a thought.

OK enough about the bong, that is not my real question, i am wondering about the cancer treatment and the repercussions of inhaling pure oxygen. Are oxygen bars good for you in moderation and bad in excess? Or should we just avoid the oxygen bars and inhaling pure oxygen all together?

Oxygen bars are generally just stupid. In the short run they're bad for you because you're throwing money away for a pretty useless service, but if you frequently visit them your lungs may actually start getting used to the higher availability of oxygen and getting complacent (IE less efficient).
It's the opposite of how people in high altitudes develop an ability to better extract oxygen from the thinner air (something which is believed to be a contributing factor to many african athletes' abilities... people who, for instance, grew up on the slopes of high mountains or plains who simply have more efficient lungs than their low-altitude peers).
