In the wake of cannabis legalization in Canada, a team of scientists has delivered encouraging news for chronic pain sufferers by pinpointing the effective dose of marijuana plant extract cannabidiol for safe pain relief without the typical “high” or euphoria that THC produces.
The number of adults currently using e-cigarettes in the UK is close to 2.9m, many of whom will have turned to the devices to quit smoking. While certainly they may help people kick the habit, there is a big problem with e-cigarettes: we don’t actually know for certain whether they are safe or not.
New research finds an association between some popular heartburn treatments and iron deficiency. Heartburn is a symptom of gastroesophageal reflux, which hydrochloric acid rising into the throat causes. This condition affects more than two million Australians.

Taking low-dose aspirin daily doesn’t preserve good health or delay the onset of disability or dementia in healthy older people. This was one finding from our seven-year study that included more than 19,000 older people from Australia and the US.
Last week I had a shocking cold. Blocked nose, sore throat, and feeling poorly. This made me think about the countless vitamins and supplements on the market that promise to ease symptoms of a cold, help you recover faster, and reduce your chance of getting another cold. When it comes to the common cold (also called upper respiratory tract infections) there is no magic cure (I wish) but some supplements may deliver very minor improvements. Here is what the latest research evidence says.
We are still in love with vitamins a century after they were discovered, with half the US and UK population taking a supplement.
