Recap
United States Drug Laws were not adequate to address the epidemic
SC Drugs do not meet strict definition of controlled substance analogs
SC drugs were eventually scheduled on emergency, individual basis

Do we test for synthetic cannabinoids?
It depends on who you are and which synthetic cannabinoids you are referring to

Immunoassay-Advantages +
Sensitive Readily automated
Inexpensive
Immunoassay-Limitations -
Class specific Cross-reactivity is unpredictable Small changes- (length of tail, steric profile of functional group) affect cross-reactivity of the drug Immunoassay may take 9-18 months to develop Different matrices will require different targets
Liquid Chromatography/Mass Spectrometry
Does not require Can be updated Definitive development of an validated in a new antibodies few days
11 3/17/2016
Blood/Serum-Advantages +
Quantitative Good for levels may be identifying recent clinically use meaningful
Blood/Serum-Limitations -
Predominantly Requires targets parent venipuncture compounds
Smoked Synthetic Cannabinoids Concentration
12 3/17/2016
Urine-Advantages +
Less invasive Easier to collect than than venipuncture venipuncture
Urine-Limitations -
Identifies metabolites- not Substitution parent and compounds (so adulteration you need to know the metabolites
Oral Fluid-Advantages +
Parent Easy- Indicates recent compound Noninvasive use detectable
13 3/17/2016
Oral Fluid-Limitations -
Does not indicate chronic use
Oral Fluid Collection
Expectoration (neat oral fluid) Collection device Cotton collection pads/swabs Cellulose pads
Oral Fluid Positivity for JWH-018 and JWH-200

Conclusions
SC use is Rapidly Evolving
We can accurately test for SC in urine, blood, hair, oral fluid
We can identify SC shortly after use (oral fluid, blood/serum) and months after use (hair)
