Here are the products I have recommended to quit smoking. I will only mention which products I think are worth it. I have not seen any evidence that these products will help many smokers. The most important thing is that a smoker will never be able to quit smoking with these products because they are so ineffective.
There will be an initial period of time where you will not be able to use the products effectively. This will include the first week, the first 2 weeks, and the first month. You will be able to smoke one cigarette a day for at least a day, but not more than 10 cigarettes in a day. If you are a smoker, you may experience some relief at first, and your pain level will decrease during this time, but the products will continue to work just as well as before. At some point, you will need to start using the products again.
No. You are free to smoke on the internet or in other places with the products, and the products don't affect your nicotine levels in any way.
