Substitutes for Tobacco Expansion
Substitutes are reviewed on the basis of ozone depletion potential, global warming potential, toxicity, flammability, and exposure potential. Lists of acceptable and unacceptable substitutes are updated several times each year. A chronological list of SNAP updates is also available.
Note: SNAP Notices and Final Rules published in the Federal Register take precedence over all information on the web site.
