Ecstasy (MDMA) has stimulant - like effects (such as increased energy) and can also cause hallucinogenic - like experiences (altered perceptions). It affects the serotonin system, which is involved in regulating emotions and sleep. Methamphetamine is mainly a strong stimulant. Heroin is a depressant. Ketamine is more of a dissociative anesthetic with hallucinogenic properties but is not typically described as having significant stimulant effects in the context of this question.
