Blood and urine samples were used. In addition, we investigated whether the severity of symptoms, in those who tested positive, was related to the blood concentration of methamphetamine. Of 285 patients who volunteered blood and/or urine samples within 48h of admission, 37 (13%) had recently taken methamphetamine. Positive psychotic symptoms between the two groups were compared by PANSS using the positive subscale.
The results showed no differences in positive psychotic symptoms between the two groups. The severity of positive psychotic symptoms in patients with three different levels of urine/blood methamphetamine concentrations, were compared.
We found no clinically or statistically significant relationship between blood methamphetamine levels and severity of psychotic symptoms.
