"Strong" doesn't mean the same for everyone. Strong nicotine, and strong tasting tobaccos, strong caffeine, and strong robust coffee, and strong alcohol content and strong flavored beer all have their grey areas.
There are some tobaccos, especially latakia blends with low nicotine that I just don't enjoy because of their stronger flavor, but strong nicotine has it's place for me. Like Workman says, if you know your tobaccos and where to place it in your day, everything is fine. I prefer to smoke the heaviest nicotine blends before bed, because I would have to take a nap directly after smoking them earlier in the day. Maybe some folks have the time for that, but I prefer to focus on flavor during the day while I am up and working.
But, give me the blond roast coffee earlier in the day while I need to get my motor running, but later in the day after dinner, I will drink a lower caffeinated coffee with a darker roast for flavor.
Alcohol just doesn't have much of a place in my day, but to each their own.
