P.S. Thanks to all the people that have taken their time to help me (and not just me, but others as well). It is much appreciated, and, from what I‘ve read, the „cold turkey“ method seems the most appealing to me. I‘ll quit smoking today, on the 7th of November 2024.
While I have no personal experience with tobacco addictions, there is an interesting literature review of CBT (cognitive behavioral therapy) and MBI (Mindfulness Based Interventions).
