After a psychotic episode, 3.2 % were prescribed stimulants and 6.8% were prescribed medicinal cannabis, with mean THC concentrations higher after the onset of a psychotic illness (31.4% vs 16.9%). Over 70% of those prescribed stimulants and 60% prescribed medicinal cannabis after experiencing a psychotic episode had further contact with mental health services due to concerns about a deterioration in mental state where these medications were thought to be a contributory factor.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>It is of concern that THC concentrations were higher in prescriptions made post-EP discharge.
