I've always heard inhaling nitrous oxide from whipped cream canisters kills brain cells, but isn't nitrous oxide used in dentistry?

I've always heard inhaling nitrous oxide from whipped cream canisters kills brain cells, but isn't nitrous oxide used in dentistry?

Yes, but safely.: Nitrous oxide is not the problem. It is the lack of oxygen that causes brain damage. When used in dentistry we never use 100% nitrous oxide, it is always mixed with oxygen. Where people get into trouble is breathing unregulated nitrous oxide on their own and depriving their brain of oxygen. They are suffocating themselves without realizing it. ...Read more

How safe are electronic cigarettes using propylene glycol as the "vapor" for asthmatics? Better than real cigarettes?

Since alcohol is a volatile liquid cannit be vaporized and inhaled like volatile anesthetics?

Since alcohol is a volatile liquid cannit be vaporized and inhaled like volatile anesthetics?

Nebulized: Alcohol has been administered in a nebulized form (very small droplets) and inhaled. I believe it was popular in some nightclubs a few years ago so patrons could become intoxicated and avoid the calories associated with ingestion. Overdose is much more likely as absorption is very rapid and doseage is difficult to judge. The volatility of ethanol is far below that of the inhalational anesthetics. ...Read more

My albuterol inhalation aerosol (warwick pharmaceuticals) helps me, but i've been switched to albuterol sulfate (pro air) which has less benefit, why?

My albuterol inhalation aerosol (warwick pharmaceuticals) helps me, but i've been switched to albuterol sulfate (pro air) which has less benefit, why?

Sensations or dose: The standard dose for a puff of albuterol is 90 micrograms, so any of the preparations should be the same in effect. Recently, the gas that pushes the medicine out of the inhaler, called the propellant, was changed. Some people feel that the new propellant (called hfa) is not as strong as what was used before. If the dose and propellant are the same, it is likely to be your sensation of effect. ...Read more

The flatulence, contain methane gas and butane gas, or only methane?

The flatulence, contain methane gas and butane gas, or only methane?

No butane. Only 20%: Of people produce methane. 99% of the gas volume does not smell. More recent evidence proves that the major contribution to the smell of flatus comes from a combination of volatile sulphur compounds (vsc).[5][12] it is known that hydrogen sulphide (h2s), methyl mercaptan, mm (also known as methanethiol, mt), dimethyl sulphide (dms), dimethyl disulphide (dmds) and dimethyl trisulphide (dmts) are present and cause the smell.Those compounds are the one percent that cause the smell.
