There is no inherent self limitation from cigarettes beyond the time it takes to smoke a cigarette. I’m not sure who you knew that smoked but I can say for certain that long-time heavy users don’t need an hour break. Quite the opposite. Abusers will hack up a lung after minutes without a cigarette puff and will wake up in the middle of the night to smoke, repeatedly.

This thread (outside your statements) is such a bizarre conversation to me that somehow people have deluded themselves into the argument a cigarette is a better option than putting in work to quit. Heroin could probably help someone stop smoking pot…that doesn’t mean it is a better choice just because “it’s harder to afford when you’re a junkie and therefore takes longer to get a hit than finding a J”.

I get the capability to abuse is easier than a cigarette, no disagreement. It’s probably similar to when smoking was allowed everywhere including on planes and in restaurants. I don’t see how the solution to ease of use, ease of access, and manufacturers adding far too much nicotine is “start smoking a different product with proven worse health consequences, including cancer, rather than vaping too much and possibly having some negative health effects”. These days nearly all major vape companies are owned by tobacco companies. They have a lot of experience in pushing the addictiveness boundaries for significant profit from the past 100+ years, and they are doing it again with vapes.

I say all this as someone who smoked for 15+ years, up to a pack and a half to two packs a day, vaped increasingly more nicotine over 5 years, and quit vaping over the course of a year by mixing 0mg nicotine liquid -- almost every vape liquid manufacturer offers it -- in fractionally increasing ratios each week until I was only vaping zero nicotine. I continued vaping 0mg for years after because I actually enjoy the act of smoking, but I finally just decided not to anymore.

Choosing not to quit and choosing not take any responsibility or steps toward battling your addictions are vastly different from not being capable. Everyone has the capacity to battle their addictions when they choose to, and small counter-examples or lack of success do not negate that premise.
