I've been hearing a lot about the dangers of e-cigarettes. Should I be worried about them?

It depends on your own health and risk tolerance, but there are some potential risks associated with e-cigarettes. For example, they may contain nicotine, which can cause addiction, as well as other harmful chemicals like formaldehyde and diacetyl. Additionally, it’s important to note that vaping is not regulated in most countries, so you don’t know what exactly is in the vapor.
