Does ghb cause permanent memory loss and adversely affect the ability to remember everyday things later?

Chronic GHB abuse has indeed adversely affected memory, ability to enjoy life, ability to cope with anxiety and stress.  For some the aftermath of GHB addiction can result in a few weeks or months of such effects.  For others the adverse effects have lasted much longer and perhaps for some they are permanent.  This is based on the experience we've had with far more than 3,000 GHB addiction cases.  GHB overdoses can potentially also have lasting adverse effects, depending on the amount of oxygen deprivation and other specific events during the overdose.
