3,4-Methylenedioxymethamphetamine, MDMA or Ecstacy is an normally illicit drug that is considered a psychoactive drug and stimulant. Just like other stimulants ecstacy causes a hyperactoviry of the Central Nervous System, resulting in hyperactivity, restlessness, euphoria, and increased sensations. However in your case Ecstasy is known as a "Club Drug" for its use in clubs and party goers.
Ecstasy, also known as MDMA, is used recreationally, so it can be called a club drug. However, it is illegal in the US, so it would be considered a narcotic as well. The effects it has are also of the stimulant variety, so they would fall under that category as well. It is definitely not a depressant.
With this information, I would choose Club Drug since it is a pretty broad definition that includes both Stimulants and Narcotics under it's umbrella.
