I'm only including the two (mostly) socially acceptable smokes, weed and cigarettes.
Personally, as I was growing up with my parents who smoked cigs, I hated it, especially during road trips where the car window would be rolled down while I was sleeping in the back just so they could smoke. Then I grew up, and gained the habit myself through peers. Before that, I was introduced to weed.
Most recently, after 11 years, I've made the conscious decision to quit cigarettes since July 24th 2020 (via the gum method), a year after my dad quit from his 40+ years of smoking on July 4th 2019.
I will still gladly smoke weed, but cigarettes have lost their favor with me recently for health reasons, and I hope that any here struggling with the same will follow suit, even if it just means cutting back. Bronchitis is no joke, I'd rather have liver failure than failure to breathe...
Made the poll unlimited since I'm sure there will be people who have multiple answers, so it'll skew things a bit, but hopefully responses will be enlightening.
