There's this myth (that came to you in pop culture) that you end up sounding like Tom Waits.
replyIn reality, some phlegm aside, their voice is still the same in any way that matters.
If you knew people who didn't smoke and started (not uncommon in the 80s and 90s, quite a few people I know started smoking in university, or after the stress of a first job, some even later), and also the inverse, you can trivially hear it for yourself.
My voice is exactly the same as before I started smoking heavily, and I have never had any of the associated problems that most people seem to have (lung capacity, stamina, infections, phlegm etc) - pot luck I guess, like most things
