Introduction



The illicit markets of New Psychoactive
Substances (NPS) have been growing
worldwide according to the 2014 UNODC
World Drug Report.
Many NPSs have not been controlled by the
UN drug conventions. Therefore, the NPS
regulation may not be fully implemented in
many countries.
In this study, the scale, patterns, and trends of
NPS misuse in Taiwan were evaluated with the
National Substance Abuse Monitoring and
Reporting Systems.

Current Status of Major Drugs of Misuse


While heroin and methamphetamine remain the two
predominant drug problems so far, ketamine misuse has
surged since 2002. A record high of 2,941 kg of ketamine
was seized in 2014. Ketamine-dependent patients
increased from 99 cases in 2006 to 1,626 cases in 2014.
Use of NPS other than ketamine was also found:
 Synthetic cannabinoids : JWHs
 Synthetic cathinones : MDPV, 4-MEC, 4-MMC, bk-MDMA
 Phenethylamines : DMA, PMMA, PMEA
 Piperazines : BZP, TFMPP
 Tryptamines : 5-MeO-DIPT
 2C-B

Conclusion




Seizures of NPSs, such as ketamine, GHB, MDPV, cathinone,
chloroamphetamine, methylone, phenazepam, and
mephedrone have been reported. Identification of these
NPS seizures by laboratory testing has also shown an
upward trend.
Most NPS users were younger in contrast to the users of
traditional drugs. Many NPS misusers have developed
comorbidities such as bladder cystitis and HCV.
The increased HIV-positive incidence may be associated
with unprotected sex and NPS use.
In summary, the epidemic level of NPS misuse and harms
may have been underestimated because of their
uncontrolled status.
