What are e-cigs?

E-cigs are electronic cigarettes. Instead of them producing smoke like a normal cig, they produce a vapor instead. E-cigs operate on a battery, and yes they contain nicotine. I view e-cigs as a tool to help someone quit smoking. At least you can use them in public places. However, don't be surprised if e-cigs get banned in the US soon. If someone just wants nicotine and no smoke, don't use e-cigs. Just simply eat potatoes and tomatoes since they contain nicotine too.
