What do you know about e-cigarettes?

I’ve never used an e-cigarette, but I’m familiar with the basic technology. E-cigarettes are battery-powered devices that vaporize a solution containing nicotine and flavorings. They typically contain fewer harmful chemicals than traditional cigarettes, which makes them safer for users. However, they still pose health risks to bystanders, as the aerosol can contain toxins like heavy metals and volatile organic compounds (VOCs).
