Smoked weed basically every day for 8 years from 16 to 24 years old. Sober for 1 week now.

I have very bad memory issues and always feel cloudy, amongst other things as well. Will my cognitive function return back to normal even though I started smoking at such a young age? I have read that a lot of the damage is irreversible, but I’m hoping that’s not the case. Thank you for all the help!

Edit: Also want to add that I was smoking multiple times a day and majority of my usage was through wax pens.
