left out methylphenidate (Ritalin), by the by I wouldn't recommend taking any of these drugs recreationally (whether you consider nicotine a drug is up to you), psychostimulants, like methylphenidate, Adderall (amphetamine salts), and Methamphetamine can all be highly addictive and it looks like others on the list are still pretty new. Well thats my dad speech of the day.
