Let me start by stating some facts:
1- Scientific information of the effects of Difluoroethane (active component of Air Duster) is scarce and in some cases contradictory.
2- I have read some studies in rats showing no evidence of significant Brain damage after a prolonged exposure to the substance.
3- Nonetheless it is widely known that the abuse of this substance can cause death.
From what I have read, people claim the high provided from Difluoroethane is merely a by-product of lack of oxygen in the brain, and the serious health issues come from the possibility of frostbites and consequently lung damage and some extra-pyramidal effects relating the heart.
Lets assume all of the above is true. If I was to obtain 100% pure Difluoroethane and release it in a balloon so that it achieves room temperature, effectively nullifying the greatest imminent health risk. And most importantly hyperventilating or even adding a 20% concentration of oxygen in the hypothetical balloon.Will..
A- Experience nothing, since I'm not having a lack of oxygen
B- Get high, disproving the fact that the lack of oxygen is the "active ingredient"
So, has any former user experienced in hyperventilation or filling balloons with Difluoroethane? Is the lack of oxygen what gets you high or does Difluoroethane affect certain neurotransmitters? If so, does anyone have hard evidence on its short-long term effects in the body and its mechanism of action?
I will kindly accept any input you have on the subject.
