Possession of a controlled substance

In Nevada, it is a felony to possess any amount of cocaine, ecstasy (MDMA), heroin, ketamine, lysergic acid diethylamide (LSD), methamphetamine, psilocybin (magic mushrooms), GHB, as well as many pharmaceutical drugs without a prescription.  It is also a felony offense to possess over an ounce of marijuana.  State penalties for possession of these drugs include up to four years in state prison and up to a $5,000 fine for a first offense.  The penalties can be harsher if the crime is being prosecuted by the federal government.
