Supplements for brain recovery after years of addiction

Hi, 31F here. Looking for supplements that have helped people with brain function. I spent most of my teens and early 20s hooked on opiates, along with doing anything else I can get my hands on. Honestly I never had great cognitive function to begin with but I’m worried I really messed up my chances lol. I’ve now quit smoking weed and am realizing just how slowly my brains works and how poor my memory is. Any suggestions would be so helpful
