But it should be noted that "additives" -such as amphetamines, caffeine, Ketamine, and hashish-have been found in MDMA seized by the Taipei police. The uncertain quality of the MDMA in Taiwan means that users are running an extra risk.
但值得注意的是，在台北市警局所查獲的 MDMA 中，發現多摻雜有其他添加物，像是安非他命、咖啡因、K 他命、麻黃素等成分，良莠不齊的品質，使得台灣的 MDMA 使用者必須面對更多的風險。
