Long-term effects of marijuana? - how to recover from heavy marijuana consumption

I stopped smoking marijuana after 7 years of intensive use. Even today I can tell a difference in my ability to think, too, I understand a bad memory and not even often, the easier questions and words. I used a straight A student and was very, very bright now .. not so much. So my question is, how long before the fade effects? Will they ever? My brain cells never recover from the violence?
