In the months before the pandemic, another mysterious lung condition was causing chest pains, stomach problems and even fever in young adults. Named Evali, it was linked to e-cigarettes and vape pens – prompting widespread concerns about their safety.

Experts later discovered that Evali was caused not by regular nicotine e-cigarettes, but by THC cannabis vapes cut with vitamin E acetate. Nonetheless, many people remain wary of e-cigarettes – even believing them to be as dangerous as cigarettes.

But while there’s still much we don’t know about their long-term effects, healthcare specialist Jamie Hartmann-Boyce says there’s good evidence that e-cigarettes have far fewer health risks than cigarettes – and are still a very effective way of helping people to quit smoking.

Meanwhile, students are back in school after a summer break in many parts of the world. Parents might have celebrated this in the past, but many will be anxious this year about COVID. We look at how they can manage this anxiety, while this week’s podcast looks at what measures work best for keeping children safe in school.

Finally, we take a different look at Europe’s ban on seal products – the difference between subsistence and commercial hunting and the impact the ban has had on the livelihoods of frontier communities living in the sub-Arctic.
