Here's a breakdown:
* The Family Smoking Prevention and Tobacco Control Act (2009) gave the FDA authority to regulate tobacco products, including cigarettes. This law requires:
* Public disclosure of ingredients: Tobacco companies must submit a list of all ingredients in their products to the FDA, which is then made available to the public.
* Reporting of harmful ingredients: The FDA requires tobacco companies to report the levels of certain harmful ingredients, including tar, nicotine, and carbon monoxide.
* Restrictions on certain additives: The FDA can ban or restrict the use of certain additives in cigarettes if they pose a health risk.
* The Federal Cigarette Labeling and Advertising Act (1965) requires cigarettes to carry warning labels about the health risks of smoking.
While these laws provide some level of transparency and regulation, it's important to note that:
* The exact composition of cigarettes can vary between brands and even within the same brand.
* The tobacco industry has a history of lobbying against stricter regulations on cigarette ingredients.
* The full range of chemicals in cigarettes, including some harmful substances, may not be fully known or disclosed.
Overall, the chemicals in cigarettes are primarily determined by the manufacturers, but there are legal requirements for disclosure and regulation of certain harmful ingredients.
For a more comprehensive list of chemicals found in cigarettes, you can consult:

Remember, smoking is extremely harmful to your health and should be avoided.
