after the patient arrives to ER
you should do a gastric lavage "pump the stomach" with activated charcoal
and use physostigmine

illicit drug would be amphetamine -in the real world supportive treatment, but since you ask physostigmine.
[usmle will give more clues because amphetamine works directly at the synaptic cleft and cocaine and TCA's work indirectly at the synaptic cleft.]

THE RIGHT ANSWER IS D.
The patient described is under the influence of a CNS stimulant, such as methamphetamine. Labetalol is a nonselective alpha and beta-antagonist that blocks many of the dangerous peripheral side effects of CNS stimulants, such as hypertension and cardiac stimulation. Other appropriate medications include antipsychotic agents (to control the agitation and psychotic symptoms) and diazepam (to control possible seizures). Supportive care should be given as needed to control the hyperthermia and to maintain respiration.
