Wrong. Flavors are simply really effective at hooking everybody.
I watched this with a friend of mine who absolutely thought the same way as you. We got him a couple different flavored ones to try--all non-nicotine.
His reaction: "Alright, you win. You have to physically take the strawberry ones away as I will absolutely drain them all."
The flavors allow the industry to find the one that you personally find agreeable. Add nicotine on top of that and you have a device for personalized maximal addiction.
Remember when Internet addiction was a big concern?
That is grossly unfair to the many of us who have absolutely nothing to do with the latest Social-Garbage-As-A-Service fads.
Just because VCs will only fund Internet Junk Food does not mean that all software that exists does that.
There is a lot of software out there that isn't dedicated to triggering human dopamine receptors. You don't hear a lot about it as it's just part of the job.
And I didn't choose to have integrity--it's just that nobody ever offered me enough money to compromise it. :)
I was just talking with some online friends yesterday who smoke and say they would never have started if it weren't for menthols, so I think you're wrong about this.
I will also note that my friends started when they were teens and no longer smoke menthols.
