So CFCs and other ozone depleting substances are causing a significant problem, and it's right to phase them out, but the asthma inhalers have mere grams of propellant per refill, and they should have allowed them to continue to have the CFC based generics for 10 years after the release of the brand name cfc-free versions.The ozone layer absorbs a portion of the radiation from the sun, preventing it from reaching the planet's surface. Most importantly, it absorbs the portion of ultraviolet light called UVB. UVB has been linked to many harmful effects, including various types of skin cancer, cataracts, and harm to some crops, certain materials, and some forms of marine life.

For over 50 years, chlorofluorocarbons (CFCs) were thought of as miracle substances. They are stable, nonflammable, low in toxicity, and inexpensive to produce. Over time, CFCs found uses as refrigerants, solvents, foam blowing agents, and in other smaller applications. Other chlorine-containing compounds include methyl chloroform, a solvent, and carbon tetrachloride, an industrial chemical. Halons, extremely effective fire extinguishing agents, and methyl bromide, an effective produce and soil fumigant, contain bromine. All of these compounds have atmospheric lifetimes long enough to allow them to be transported by winds into the stratosphere. Because they release chlorine or bromine when they break down, they damage the protective ozone layer.
...
...numerous experiments have shown that CFCs and other widely-used chemicals produce roughly 84% of the chlorine in the stratosphere, while natural sources contribute only 16%.

The initial concern about the ozone layer in the 1970s led to a ban on the use of CFCs as aerosol propellants in several countries, including the U.S. However, production of CFCs and other ozone-depleting substances grew rapidly afterward as new uses were discovered.
Through the 1980s, other uses expanded and the world's nations became increasingly concerned that these chemicals would further harm the ozone layer. In 1985, the Vienna Convention was adopted to formalize international cooperation on this issue. Additional efforts resulted in the signing of the Montreal Protocol in 1987. The original protocol would have reduced the production of CFCs by half by 1998.
After the original Protocol was signed, new measurements showed worse damage to the ozone layer than was originally expected. In 1992, reacting to the latest scientific assessment of the ozone layer, the Parties to the Protocol decided to completely end production of halons by the beginning of 1994 and of CFCs by the beginning of 1996 in developed countries. More information on the phaseout of ozone depleting substances is found here.
Because of measures taken under the Montreal Protocol, emissions of ozone-depleting substances are already falling. Levels of total inorganic chlorine in the stratosphere peaked in 1997 and 1998. The good news is that the natural ozone production process will heal the ozone layer in about 50 years. More information on the current state of the ozone layer is found here.
The Montreal agreement allows for essential use cases to be petitioned by companies who can demonstrate their use of the CFC was necessary. The EPA and FDA work together to determine when CFC metered dose inhalers can be banned:I know all of that. I'm talking about the push to phase them out in 2008. The movement to phase out CFCs from consumer products and the more recent banning are separated by almsot 20 years! It makes me think there is more to the story than a simple continuation of a 20 year old movement.
There are actually three brand versions of CFC free albuteral inhalers now, and no generics. There are supposed to be programs intended to help out low income users to help offset the increase in cost. My doctor didn't bring this up (though I specifically asked whether she specified generic drugs or not), perhaps it's a more frequent topic of conversation in lower income areas.EPA coordinates with the United States Food and Drug Administration (FDA) to determine which CFC MDIs continue to be essential for public health as alternatives penetrate the market. In 2005, FDA removed the essential use designation for albuterol used in oral pressurized MDIs as of December 31, 2008. As of December 31, 2008, CFC-albuterol MDIs cannot be sold, distributed or offered for sale or distribution in interstate commerce pursuant to Section 610 of the Clean Air Act
My question is why? Some person or committee of persons was involved in that decision. "EPA coordinates" is hardly descriptive of their input level. It also doesn't eliminate the possibility that other interested groups provided input either. Companies have requested FDA action in the past to implement bans: http://www.nytimes.com/2012/07/18/science/fda-bans-bpa-from-baby-bottles-and-sippy-cups.html?_r=0In 2005, FDA removed the essential use designation for albuterol used in oral pressurized MDIs as of December 31, 2008.
So it could have been objectively determined even if the drug companies didn't submit their own comments (which I'm sure they did).Under 21 CFR 2.125, several criteria must be met for a listed product to be considered no longer essential. These criteria are the following:
- Sufficient non-ODS alternatives are available with the same indications and approximate level of convenience;
- There is adequate post-marketing data for the alternative products.
- Supplies are adequate to meet the demand;
- Patients who require the product are adequately served; and
HHS/FDA initiated notice and comment rulemaking in June of 2004 to allow public input into the determination. The agency received over 75 comments. After thoroughly reviewing and evaluating the comments received, and in consultation with other federal agencies, HHS/FDA has determined these conditions will be met by December 31, 2008, which will render the use of CFCs in albuterol MDIs no longer essential.
Apple V Samsung?The current practice of patent-it-and-then-raise-the-price-obscenely is not limited to inhalers.

(I was trying to find a story I read about a company which was awarded a patent, sued to shut everyone else down, then raised the price several thousand percent, but I could not find it. So I offer the above linked story instead)
Neither Apple nor Samsung raised the price of their product(s) several thousand percent and basically told people "Either pay the new price for your life-saving meds or else die, we don't care about anything but your money" after securing their monopoly. That's something that seems to be confined to the pharmaceutical industry.Apple V Samsung?

Ok, life-saving, I'll grant you. Change it to life-eating, maybe.and basically told people "Either pay the new price for your life-saving meds or else die,
we don't care about anything but your money"
Well, thankfully, they haven't come that far yet... but they're trying, hard. And they've made more progress than I can believe a sane judge would allow.after securing their monopoly.
How so? They're still not even close to the dominant computer company. The iPad/iPhone still have plenty of competitors out there. I'm not really seeing your point here.Well, thankfully, they haven't come that far yet... but they're trying, hard. And they've made more progress than I can believe a sane judge would allow.
They have a patent on rectangles with rounded corners.How so? They're still not even close to the dominant computer company. The iPad/iPhone still have plenty of competitors out there. I'm not really seeing your point here.
Pessimist.Yet.
Why thank you.Pessimist.
Pushback? Neither vendor has ever raised their prices several thousand percent. If anything, Apple has gotten into more trouble by lowering their prices (IIvx, original iPhone). Dunno about Samsung.TODAY you learned that? Anyway, my first foray down this line of conversation was made with tongue in cheek, but once pushback developed over it..
We responded seriously to his joking:Pushback?
So he ran with it, though it really wasn't something he actually cared about.Apple V Samsung?
That's what I thought, but it looks like what he really likes to do is bicker.He just likes to argue.
A lot.

Bickering is just a form of arguing. So you can argue and bicker, and you can just argue, but you can't bicker without arguing.View attachment 9124
People, People! This is supposed to be a 'appy occasion! Let's not bicker and argue about who's arguing and who's bickering...
