Herbal cigarettes are not a nicotine substitute. They do not contain nicotine and are typically made from a mixture of herbs and other non-nicotine ingredients. The other options—nicotine gum, nasal spray, and nicotine patches—are all products specifically designed to deliver nicotine as part of a smoking cessation strategy.
