A friend of mine is a Doctor. This is what he suggests to anyone who is truly interested in stopping.
Smoke as much as you need to
Start rolling your own, unfiltered.
Put the pack somewhere inconvenient, like car trunk or in a hard to reach box in the garage
Only every smoke outside, under an open sky. No cars, no houses, no awnings, no umbrellas, etc. No matter the weather.
He says this makes it accessible but inconvenient and not as enjoyable. Eventually the inconvenience will start to outweigh the need until you end up quitting. He says he has like a 80-90% success rate with those who actually follow through
