Cigarettes are worse than e cigs, because they can cause cancer, the nicotine addiction is far more addicting, and the harm caused to the body is more life threatening. Cigarettes in the past have been linked to cancer, most notably lung cancer, which is one of the leading causes of death in the United States. The addiction to nicotine from cigarettes is far worse, for it comes straight from the tobacco and e cigs/vapes have a controlled amount of nicotine in the juice. The harm the smoke/nicotine from cigarettes causes can ruin your gums and teeth, lungs, and even day to day life just based on having to stop to make smoke breaks. The effects on the gums, teeth and lungs and end up in loss and even death.
