70.5% of respondents from the rave community reported ketamine use on the current TRIP! Survey (2010)Disturbed sleep (66%) and memory loss (56%) were noted as primary consequences commonly associated with drug useOpen-ended responses indicate common health problems and Open-ended responses indicate common health problems and concerns associated with ketamine use such as ulcers, k-pains, sleep disturbance and memory problemsAlmost half of all ketamine users had reported having unpro-tected sexKetamine users were also poly-drug users: MDMA (99%), alco-hol (97%), pot (95%), mushrooms (90%), coke (88%), acid (80%), synthetic opiates (80%), and 64% crystal meth 80% of ketamine users wanted to know more about mental health

As part of a more extensive survey aimed at identifying trends related to drug use, we investigated the preva-lence of ketamine use and its associated effects among members of the dance and rave community in Toronto.

Over 146 members were recruited on the TRIP! Project’s Facebook to complete an online drug survey.

The survey was approved and administered in accor-dance with the Ryerson University Ethics Review Board guidelines.

Adolescents in Toronto are using ketamine, particu-larly in the dance and rave community, where the rate of use appears to have rapidly increased.

Indeed, the current estimate more than doubles that reported in the 2004 TRIP! study.

These findings highlight that health service providers should be educated about the mental and physical ef-fects of ketamine use to adequately serve the needs of this population.

Ketamine (“Special K”) is an increasingly prevalent drug in today’s society.Like its predecessor PCP (“angel dust”), ketamine is a dissociative anaesthetic that blocks NMDA receptors in the brain.A 1997 survey report from the U.K. reported that 32 % of A 1997 survey report from the U.K. reported that 32 % of club goers had used ketamine and by 2004 use had in-creased to 43% (Mixmag, 1997, 2004).The Ontario (Canada) Student Drug Use and Health Survey (2009) reported that 1.6% of high school students had used ketamine in the past year. A previous study by TRIP!
