New Psychoactive Substances (NPS)
continue to be identified, and it appears that moves by the United Nations and
by individual countries to control lists of named NPS may be encouraging the
development of yet further variants to avoid these controls.
In response to the ever-expanding range of NPS being developed, we have
produced an extensive line of reference materials that meet the rapidly
changing demands of the NPS landscape, many of which are produced under the
rigorous quality assurance standards set out in ISO Guide 34.
