If there’s one thing that unites all countries and cultures, it’s our love of caffeine. Whether it’s coffee, tea or other foods, caffeine is the most widely consumed drug in the world — more than alcohol, and more than tobacco: 90% of adults worldwide consume caffeine daily. At doses found in food and beverages, the effects are predictable and the side effects are slight. But natural or not, caffeine is a drug; isolate the pure substance, and the risks change. It would be difficult for most people to drink 16 cups of coffee in a row, but that’s the equivalent of just one teaspoon of caffeine powder. If that doesn’t hospitalize you, a tablespoon of the powder will probably kill you. Yet despite the risks, there are no restrictions on the sale of caffeine powder. You can buy a 1kg bag for $35, which provides the caffeine of about 5,000 cups of coffee. Caffeine powder is freely available to buy because regulators treat it differently – not because of its inherent properties, but because it’s “natural” and sold as a dietary supplement rather than a drug. This is a regulatory double-standard that harms consumers. It’s leaving a body count. And it needs to change: (more…)

Besides the acute conditions, the chronic problems are starting to appear. Our osteoarthritis years are here.
As the available pharmacist, I get a lot of questions about joint pain. What’s reassuring, I tell them, is that they shouldn’t blame running. Osteoarthritis is common — the most frequent cause of joint pain. For some, it starts in our twenties, and by our seventies, osteoarthritis is virtually certain. Regardless of your level of exercise, the passage of time means the classic osteoarthritis symptoms — joint pain and morning stiffness, that worsens over time.
Osteoarthritis progresses gradually. Blame biomechanics and biochemistry. It starts with a breakdown of the cartilage matrix. Stage 2 progresses to erosion of the cartilage and a release of collagen fragments. Stage 3 is a chronic inflammatory response. The goals of treatment are to reduce inflammation and pain, and stop progressive disease. There’s no drug therapy that’s been show to actually improve joint function. Reduce pain, or slow inflammation, yes. Analgesics, like Tylenol, and anti-inflammatories are mainstays. But repair damage? Sorry: you lose it, it’s gone. Chondrocytes don’t seem to be able to repair the overall matrix — which is made mainly of collagen. (more…)
