There’s no proof that electronic cigarettes are safer than their paper and tobacco counterparts according to Greek scientists worried by their growing popularity. “In the British Medical Journal, they say that without more evidence it is impossible to know if such products actually do more harm than good. Some studies have raised safety fears, but retailers argue e-cigarettes are a healthy alternative to the real thing. Users can inhale nicotine without tar, tobacco or carbon monoxide. The Department of Health suggested consumers ‘exercise caution’. The report authors said consumers should stop using the devices until ongoing safety studies reported back within the next year. The World Health Organisation is among those to raise concerns about the safety of these new types of cigarette substitute, which deliver a nicotine hit in a fine vapour. And in the past year, US regulators have detained and blocked numerous shipments of e-cigarettes at borders because the devices are not approved.”
