The results are similar, statistically, because most any addiction is “finally” ended, with no more relapse, when the person finally simply decides to take control, and quit, in spite of the pull of the addiction and with or without medical/drug support.
Some people will use medical/drug support to help them get to the point where they will take control (because they believe they need it); and some people will go it alone. But success comes with sustaining the decision to quit (take control of the choice) and, at least statistically, the success and relapse rates are about the same.
However, it is a statistic, and therefor IT DOES NOT MEAN that the medical/drug support is not helpful IN SOME CASES.
I have quit cold turkey and stayed off for 5 or more years three different times. I am now on year 8 of the third attempt; I think I’ve finally beat it. Of course, nearly $10 a pack will definitely keep me off of them!
Yep, another way to look at the results is: “over-the-counter medication such as nicotine patches are just as effective as cold turkey.”
So use whichever you wish.
But no federal funding either way.
