Yes and no. There appear to be both reversible brain damage and permanent brain damage from drugs and alcohol. Abusers of these substances tend to have nutritional deficiencies, lacking essential vitamins and minerals to counteract the toxicity to the brain cells from these drugs. Stopping the abusive substance, restoring a good metabolism, and preventing nutritional deficits may reverse some of the damage. However, chronic and prolonged drug abuse often leads to irreversible brain damage.
