The prevalence of positive methamphetamine test in patients referred to the emergency department was 1.2%, which was significantly higher in men (P = 0.017). The mean age was 39.9 ± 17.2 years. Methamphetamine users were more likely to be traumatized than the general population. There was a statistically significant difference in seizure (P = 0.003), chest pain (P < 0.001), tachycardia (P < 0.001), palpitation (P < 0.001), HTN (P = 0.002), tachypnea (P = 0.001), visual hallucinations (P = 0.001), auditory hallucinations (P = 0.001), paranoia (P = 0.001), grandiosity (P = 0.035), talkativeness (P = 0.001), suicidal ideation (P < 0.001), homicidal ideation (P = 0.001), violence (P < 0.001), and disorientation (P < 0.001) in positive methamphetamine test group.
