Have I caused permanent damage?

I used to have bad habits. My vitals all look good. I quit vaping/smoking forever at 27.5. My blood pressure is fair/ideal, 118/78 and 83 beats. BMI ideal, 6ft0.5 and 173 lbs. 15% body fat. Gonna get my lipid profile checked. I do weights 2X a week and a bit of cardio and walking. I get good sleep, rest and have a stress free life. I plan to keep this.

my habits - I started vaping at 19. I then started smoking at 21 mostly light/mod, then there were many months of smoking a pack a day and chain smoking, then I just went back to vaping as it’s less harmful but I’ve probably had years of smoking a disposable vape a day and chain vaping it. In university I also used to drink excessively.

I quit mainly because I’m health conscious and I also noticed it affecting me like the vaping suddenly made my lungs really tight and I couldn’t exercise as hard but when I quit this all went back to normal after a couple months
