Are there cigarettes with no nicotine?

Herbal cigarettes that don't contain nicotine are available. In fact, they're what actors on TV and in the movies smoke, because smoking tobacco in the workplace (in this case, the set) isn't allowed in most states. Just because these products lack nicotine doesn't mean they're safer than tobacco cigarettes or even safe at all. Herbal cigarette smoke contains plenty of chemicals that are known to cause cancer.
