Caffeine for ADHD
“I don’t want to give my child any drugs or chemicals for their ADHD,” says a parent. “Instead, I’m thinking about using caffeine. Sound strategy?” It may be dispensed by a barista and not a pharmacist, and the unit sizes may be small, medium and large, but caffeine is a chemical and also a drug, just as much as methylphenidate (Ritalin) is....
Pseudoscience Sells
It is an unfortunate truth that there is money in pseudoscience, particularly medical pseudoscience. Money both attracts charlatans and also funds their activities, which includes marketing pseudoscience and defending their claims from scientific scrutiny. In this way the game is rigged in favor of pseudoscience. With0ut effective regulation, sites like ours are forced to play whack-a-mole with the medical pseudoscience du jour....
TIME Magazine, Dr. Oz, What to Eat, and Supplements
Here on SBM we have frequently had cause to criticize the media for poor science reporting and for spreading misinformation. Among many other individual offenders, we have criticized Dr. Oz for promoting alternative medicine on his TV show and gullibly promoting guests who pretend to talk to the dead and pretend to heal people with carnival sideshow tricks. We tend to be...
Chemotherapy doesn’t work? Not so fast…
A favorite claim made by cancer quacks (and quacks of all varieties, actually) is that chemotherapy doesn't work. One variant of this claim is what I call the "2% gambit." Basically, this gambit claims that chemotherapy is only 2% effective. Not surprisingly, the evidence backing up the "2% gambit" is a highly flawed study, as is the evidence used by quacks to...
Gullible George: A monkey goes to the naturopath
I get the occasional email. Very little hate mail, unfortunately, since hate mail is often more amusing. I read what little email I receive, and usually do not respond, mostly as I do not have the time. I am a slow writer and a slower typist, and there are just so many hours in the day, and the older you get, the...
Quoth the anti-vaccine group SANE Vax: Beware HPV DNA in Gardasil!
Every so often, there’s a bit of misinformation that starts spreading around the Internet that shows up in enough places that our readers take notice and e-mail us about it. What happens is that these in essence become “requests.” We at SBM are, of course, happy to consider all requests and sometimes will actually take them on, particularly when doing so will...
Comparative Drug Research
The latest issue of the BMJ contains an editorial recommending that regulators (this is in the UK, but the argument applies in the US and elsewhere) should require pharmaceutical companies to provide research on direct comparison to existing therapies as part of the approval process. The authors, Sorenson, Naci, Cylus, and Mossialos, write: When a drug comes to market, evidence on the...
Menstrual Synchrony: Do Girls Who Go Together Flow Together?
When women live together, do their menstrual cycles tend to synchronize? It’s been a long time since I first heard that claim. I didn’t believe it, for a number of reasons. I had never observed it myself, I saw no plausible mechanism to explain how it could happen, I thought the statistics to prove it would be problematic and complicated, and I...
Economically-Motivated Herb Adulteration
As early as 2006, I used to be able to write monthly about US FDA warnings on erectile dysfunction supplements being found adulterated with prescription drugs such as sildenafil, the phosphodiesterase-5 inhibitor found in Viagra. These adulteration episodes raised the question of how many anecdotal reports of herbal products “working” had to do with them containing approved medicines. So common was this...
Who’s to Blame for Drug Shortages?
All the best effort to practice science-based medicine are for naught when the optimal treatment is unavailable. And that’s increasingly the case – even for life-threatening illnesses. Shortages of prescription drugs, including cancer drugs, seem more frequent and more significant than at any time in the past. Just recently manufacturing deficiencies at a large U.S.-based contract drug manufacturer meant that over a...
