Tobacco kills more people than all other drugs combined. The effects of smoking cause heart attacks, lung cancer, oral cancer, memory loss, and countless other diseases. The reason for these health problems is that each cigarette is filled with more than 200 different toxins including nicotine, a drug so powerful that it's more addictive than heroin. Furthermore, second-hand smoke affects countless innocent people who end up suffering for someone else's bad addiction. For this reason, smoking is more dangerous and less excusable than other drugs.
