Cold Turkey Is Best
Forget nicotine patches, the best way to give up smoking is by going ‘cold turkey’.
Scientists say health authorities make quitting sound harder than it is by bombarding people with an array of drug replacement therapies they don’t need.
A study found three out of four smokers gave up without any help, despite pressure from drug companies and doctors who offer gums and patches.
Health authorities and advertisers make quitting sound impossible without the aids, so many people never bother trying.

You are right. It would appear that the Glaxos of this world have a strong sway on the medical profession, and keep feeding the public misinformation to perpetuate the myth that you need to buy their products. To quit smoking you stop taking nicotine, not change the method of delivery.
