Among the challenges that now face forensic toxicologists is the extraction, confirmation, and quantification of synthetic cannabinoids and synthetic cathinones, many of which are new to both the enforcement agencies and analysts alike. Synthetic cannabinoids are defined as designer drugs that are chemically different from the chemicals in cannabis but which are sold with claims that they will provide similar effects. When these chemicals are sprayed or otherwise soaked into a base material which is often plant-derived, the finished product is sometimes misleadingly called synthetic marijuana. These products are often sold for recreational drug use to avoid being classified as illegal There are several psychoactive artificial cannabinoid families (e.g. JWH, AM, HU, and CP) that are sold under brand names like K2 and spice, both of which are now used as generic terms used for any synthetic cannabinoid product.
Synthetic cathinones are compounds derived structurally from Cathinone(also known as β-keto-amphetamine), a monoamine alkaloid found in the shrub Catha edulis (khat) that is chemically similar to ephedrine, cathine, methcathinone and other amphetamines.. Cathinone differs from many other amphetamines in that it has a ketone functional group. Other phenethylamines that share this structure include the stimulants methcathinone, MDPV/PDV, mephedrone which also fall under the category of Newer Psychoactive Compounds (NPS)
UCT is at the cutting edge of not only developing methods/applications for these two emerging classes of compounds, but also supporting forensic toxicologists with their analysis through the use of Silica Clean Screen® THC and DAU sorbents and polymeric HLD sorbent These chemical phases can be supplied in 1, 3, 6 and 10 mL formats with 50 to 200 mg bed masses in addition to well plate formats (48/96).
