A Study on the Cognitive Impairment and Other Harmful Effects Caused by Ketamine Abuse (2005)

A Study on the Cognitive Impairment and Other Harmful Effects Caused by Ketamine Abuse (2005)

  1. Jatelka
    A report by the Narcotics Division, Security Bureau, Hong Kong Special Administrative Region Government

    Includes some interesting stuff on the epidemiology of ketamine use in Hong Kong.

    1. This is a study on the harmful effects of abusing Ketamine among young people in Hong Kong. The study consists of two parts. The first part is a cross-sectional study comparing the health related outcome measures among three groups of subjects namely primarily Ketamine users, Ketamine polydrug users and non-drug user control. The second part is an in-depth qualitative study on the subjects primarily abused Ketamine. The objectives of the first part comparison study are:

    a. To assess the physical and psychological dependence potential of abusing Ketamine, and identify their
    withdrawal symptoms and factors that modulate the addictive potential of Ketamine
    b. To explore the consequential effects of Ketamine on the cognitive function of abusers

    2. A total of 101 drug abusers, fulfilling the inclusion criteria1 for the study and 26 control subjects have been recruited. Very few subjects abused only one type of drug. Most of them were polydrug users. There were 24 primarily Ketamine users, 6 primarily Ecstasy users and 71 polydrug users recruited. All the polydrug users abused Ketamine together with other psychotropic drugs. Since the number of Ecstasy was too small for meaningful statistical comparison, analysis of Ketamine abusers was focused in this study. The outcome measures were compared among primarily Ketamine group (N=24), Ketamine polydrug group (N=71) and non-drug control group (N=26).
