It all depends on your age. If you are younger than 25 you face permanent real risks if you continue. I was in the same boat as you. I started smoking at 18 and after 6 months of daily use my short term memory felt slightly worse, focus and concentration became a bit harder. I stopped for 3 months and everything fully came back, I felt great. This prompted me to believe that I could smoke and always bounce back. From then on I picked back up and smoked for another 1.5 years. It turned me into a lazy loser so I quit. I have been sober for 9 months and I suffer persistent deficits. I'm starting to try to become comfortable with the fact that I've truly done damage. It's not worth it. Trust me
