I never found nicotine addictive. It never compelled me to increase my consumption beyond a few cigarettes a day, usually in social settings. I never became a regular purchaser of cartons of cigarettes. It was purely a social activity as most my peers were smokers and participating in the smoke breaks was a huge part of socializing. But it never escalated beyond that, there was simply no draw and stopping cold-turkey was completely uneventful with zero physiological effects.
Coffee however, has such a profoundly stimulating effect on me, it completely derails my life for days after a lone day of consumption. It's a very on-vs-off modal existence, and if I fall into the on mode for more than a couple contiguous days, I begin craving it and actively seeking it out. And when I manage to finally resist those cravings, I end up going through ~three days of hangover-like withdrawal hell which if I'm not up for enduring will just push me back on the wagon to make it stop.
For me, coffee/caffeine is far more sinister and addictive than cigarettes.

"Conclusion: Dependence to traditional cigarettes and snus seem to be relatively similar while NR (nicotine replacement) was rated lower and coffee lowest."
For a long period of time I only drank coffee during the week and not weekends, sometimes I stopped some summers and when I slept badly I stopped drinking coffee for a while. No problem at all with any of that.
I do like like the small energy burst in the morning when I'm working and I like the ritual when it is winter in Sweden it is dark and cold outside and you are freezing, then drinking a cup of coffee as you start up your computer is nice.
"don't drink coffee, coffee! The Turkish potion is not for kids, weakens the nerves, makes you pale and sick. Don't be a muselman (muslim, archaic), who can't do without it"
My almost 90 year old grandmother still talks like this about coffee and many people forget nowadays how bad of a reputation coffee had in the West until it got really popular, and despite not having many obvious bad health effects, and maybe even having positive ones.
And sadly often a lot of it is tied to the image of the "sickly Turk" which is a popular stereotype attached to most things imported from 'oriental' cultures. You may remember debates about the hookah craze a decade ago or so.
If she is 90, maybe this is some sort of propoganda fallout from WW1 induced shortanges?
