The Food and Drug Administration’s 2016 Deeming Rule classified e-cigarettes and other vaping materials as tobacco products and imposed strict regulations on what vaping entrepreneurs can say to their customers, even though advocates say these technologies can reduce the harm from smoking and help some smokers quit entirely. In response, the Pacific Legal Foundation (PLF)  is taking FDA officials to court on behalf of small business owners on the grounds that the rules violate free speech and were enacted unconstitutionally. Joining us is Thomas Berry, Attorney at the Pacific Legal Foundation who is leading this legal effort.
