This patient most likely consumed 3,4-methylenedioxymethamphetamine (MDMA).

MDMA, also known as "Molly" or "ecstasy" is a recreational drug with sympathomimetic properties accomplished by its increase release of endogenous catecholamine and inhibition of catecholamine re-uptake. It also increases serotonin levels. Patients can present with hyperthermia, hypertension, and tachycardia; as well as, increased alertness and feelings of increased physical and mental powers. Patients may be hyponatremic due to their increased water intake and, in some patients, persistent anti-diuretic hormone release.

Answer 3: PCP intoxication presents with belligerence, impulsiveness, homicidality, psychosis, psychomotor agitation, vertical and horizontal nystagmus, tachycardia, and ataxia.
