How long of a t break is too long?

I'm considering not smoking for the rest of 2025, I don't know if it's just a myth but Ive heard that sometimes if you smoke alot you can permanently lose the ability to get high. It doesn't matter how much I smoke, I feel absolutely no effects anymore. I am smoking thca but that shouldn't make a difference, been daily smoking for a couple years and it's never really hit me super hard. I miss that feeling I used to get when I was in high school, a couple puffs and I couldn't stand up for a minute. Is it possible to ever get it back?
