The Popular Over-The-Counter Cold Medicine That Science Says Doesn't Work (forbes.com)
HughPickens.com writes: Back before methamphetamine cooks started buying up non-prescription decongestants to brew crank, all of us were able to buy effective decongestants right off the store shelf without a problem. Now David DiSalvo writes at Forbes that to fill the store-shelf void, drug companies substituted the already-FDA approved ingredient phenylephrine for pseudoephedrine. But the oral decongestant phenylephrine simply doesn't work at the FDA-approved amount found in popular non-prescription brands, and it may not even work at much higher doses. Researchers at the University of Florida are asking the FDA to remove oral phenylephrine from the market. "We think the evidence supports that phenylephrine's status as a safe and effective over-the-counter product should be changed," says Randy Hatton. "We are looking out for the consumer, and he or she needs to know that science says that oral phenylephrine does not work for the majority of people."
In 1976, the FDA deemed a 10 milligram oral dose of phenylephrine safe and effective at relieving congestion, making it possible for companies to use the ingredient without conducting studies. But Leslie Hendeles and Hatton say phenylephrine does not effectively relieve nasal stuffiness at this dose. They say the FDA cited four tests demonstrating efficacy at the 10 milligram dose, two of which were unpublished and sponsored by drug manufacturers. In contrast, the FDA cited six tests demonstrating no significant difference between phenylephrine and placebo. Hendeles said a higher dose may work, but no research has been published regarding safety at higher doses. "They need to do a dose-response study to determine at what higher dose they get both efficacy and safety," says Hendeles adding that until then "consumers should go that extra step and get it (pseudoephedrine) from behind the counter."

Furthermore, the FBI's own stats show that the ban/restriction on pseudoephedrine has made the problem worse. Before the ban, meth was mostly a mom & pop business. For the next 2 or so years after the ban meth sales dropped, but then the mexican cartels more than filled the gap with wholesale production (like Breaking Bad style industrial manufacturing importing the raw ingredients from China) and now instead of little guys who are mostly dumbasses selling to their neighbors you've got organized crime networks all over the country.
Meanwhile I don't feel safe buying a sudofed and there are a bunch of stories of people being arrested for having bad allergies. I don't have the link handy, but the very first person arrested for buying too much was buying it for his kid.
Yeah but pseudoephedrine relieves all congestion, not just nasal.
