For nearly a decade, abstinence-only (i.e. no nicotine use) advocate John Polito at WhyQuit.com
http://whyquit.com/whyquit/LinksCAids.html (see many other postings on this issue at end of that article) has been criticizing drug industry smoking cessation products, and has exposed lots of drug industry funding conflicts of interest for most authors of the US PHS
tobacco Treatment Guidelines at

Several months ago, Greg Connolly and Hillel Alpert (at Harvard) published an article finding that NRT products were not effective for smoking cessation, and urged FDA to only approve smoking cessation drugs that are effective (i.e. ban the sale of NRT).
There are also many anti
tobacco extremists in CA who do not support NRT (because they also believe NRT keeps smokers addicted to nicotine, and prevents/delays them from quitting smoking).
It is important to realize
tobacco harm reduction advocates are fighting two distinctly different entities (abstinence-only prohibitionists and NRT/Chantix lobbyists/researchers/promoters that are funded by the drug industry), although many/most executives/staff at these drug industry funded groups (CTFK, ACS, AHA, ALA, AMA, ADA, ATTUD, Legacy, etc.) are also abstinence-only tobacco prohibitonists.
But while some abstinence-only prohibitionists oppose NRT products/use, many more abstinence-only prohibitionists have had a marriage of convenience with the drug companies (because the latter funds the former).
