Predominantly, respondents were from Germany, England and Denmark. Within the past year, 8.55% met the criteria for ketamine dependence. Respondents who used ketamine in their lifetime tended to be young (mean (x\u0304)\u2009=\u200927.37\u2009years), men, heterosexual and of white ethnicity. Younger age (x\u0304\u2009=\u200924.84\u2009years), gay sexual orientation, student status, past-year use of other drugs and no lifetime mental health diagnosis were associated with past-year ketamine use.
