I don’t know much about all the carcinogenic materials contained in tobacco products, but it has been widely reported that cigarettes contain around 4,000 distinct chemicals, of which many have negative effects on the human body. Electronic cigarettes, on the other hand, are often claimed to contain far fewer toxic agents than cigarettes. However, there are currently no FDA regulations or conclusive studies on the contents of e-cigarettes. Therefore, any claims to the effect that e-cigarettes are safer than traditional cigarettes is purely marketing speak.
The types and quantities of toxic agents that currently exist in e-cigarettes are largely dependent on what each manufacturer decides to include, knowingly or unknowingly. Your guess is as good as mine. Until such time as there has been sufficient testing, and implementation of rules and regulations, there cannot be a serious comparison. Don’t be fooled by the claims that e-cigarettes are safer than traditional cigarettes. After all, poison is poison, and carcinogens are carcinogens. Leave the expertise up to the experts!
In the meantime, my advice would be not to trade in one for the other, but to get rid of both!
