I disagree with your conclusion. It seems to me that if you have an equal chance of long-term success with either method, that you should choose whichever method is most effective for you, personally. If you want to quit smoking and cold turkey works for you, then go for it. But if you relapse with a cold turkey approach, you have the option of either trying it again or trying one of those products.
It’s not my conclusion. I’m just a dumbass with an internet connection.
My only point is that intelligent grown adults with life experience know enough to ask when it comes to any dealings in life is...
“What is their motive”?
“Why would they lie?”
Conflict of interest.
