抄録

　2002年から2014年に豊島病院精神科に危険ドラッグ使用による精神症状で緊急措置鑑定を要した40症例の特徴について検討した。危険ドラッグ使用者は若年男性に多く，危険ドラッグ使用開始以前の措置入院の経験は2割以下だった。危険ドラッグ使用者による措置入院者数は2012年頃より増加し，2014年夏頃より急速に減少していた。規制の強化が奏功し危険ドラッグの使用による措置入院患者は減少傾向である。危険ドラッグの毒性の強さは既存の違法薬物より強力な可能性が示唆された。危険ドラッグの長期的影響の研究，包括的な薬物乱用を阻止する仕組みの整備が必要である。

　The aim of this study was to clarify the clinical features and trends of designer-drug-abusing patients through comparisons with patients who have used other illegal drugs in addition to designer drugs. We retrospectively researched 40 cases, which were who required underwent examinations at Tokyo Metropolitan Health and Medical Corporation Toshima Hospital psychiatric emergency in 2002-2014. Many of the patients were young male, and the rate of having experienced of compulsory hospitalization were less than 20% despite they had use other illegal drugs. The results suggest that the psychotic effect of designer drugs were stronger than conventional illegal drugs. The number of designer-drug abusing patients has increased from 2012, but it has rapidly decreased in 2014. Tighter legal controls may have contributed to a reduction in designer-drug usage, but an establishment of more comprehensive system for drug abuse prevention should be required.
