Description This strip is made for the detection in human urine of " K2 " or " Spice " type of synthetic cannabinoids synthetic cannabis. Total binding was defined as the amount of radioactivity observed when 0. Specific binding was calculated by subtracting non-specific from total binding.

After overnight extraction, bound radioactivity was determined by liquid scintillation spectrophotometry. Specific binding is expressed as a percentage of binding occurring in vehicle samples e. Louis, MO and water ad libitum until immediately before testing. Animals were acclimated to the laboratory environment 2 days prior to experiments and were tested in groups of 6 mice per condition. All studies were carried out in accordance with the Declaration of Helsinki and with the Guide for Care and Use of Laboratory animals as adopted and promulgated by the National Institutes of Health.

A rostral-caudal cut approximately 1. At least 7 days were imposed between surgery and experimental observation of drug effects to allow incisions to heal and mice to recover normal body weights. Following surgery, implanted mice were individually housed in Plexiglas mouse cages Implanted transmitters produced activity- and temperature-modulated signals that were transmitted to a receiver model ER Receiver, Mini Mitter Co. Albans, VT equipped with exhaust fans, which further masked ambient laboratory noise.

On experimental days, mice were weighed, marked, and returned to their individual cages during which at least 1 hr of baseline data were collected. Cannabinoid doses were then calculated and drugs prepared for injection. Mice were then placed into a new cage with fresh bedding to stimulate exploratory behavior. Temperature and locomotor activity data were collected at regular 5-min intervals and processed simultaneously by the Vital View data acquisition system Mini Mitter Co.

Curve fitting and statistical analyses for in vitro experiments were performed using GraphPad Prism version 4. The Cheng-Prusoff equation [61] was used to convert the experimental IC 50 values obtained from competition receptor binding experiments to K i values, a quantitative measure of receptor affinity. Non-linear regression for one-site competition was used to determine the IC 50 for competition receptor binding. For core body temperature experiments, the area under the curve AUC was calculated using a trapezoidal rule from 0—10 hr.

For locomotor activity, total locomotor counts were summed from 0—10 hr. The authors would like to thank Ms. Browse Subject Areas? Click through the PLOS taxonomy to find articles in your field.

Abstract Background K2 products are synthetic cannabinoid-laced, marijuana-like drugs of abuse, use of which is often associated with clinical symptoms atypical of marijuana use, including hypertension, agitation, hallucinations, psychosis, seizures and panic attacks. Download: PPT. Figure 1. Figure 2. Figure 4. Figure 5. Discussion This study importantly demonstrates for the first time that five potential Phase I hydroxylated metabolites of the synthetic cannabinoid JWH bind with high nanomolar affinity to, and very efficaciously activate, CB1Rs in vitro.

Statistical Analysis Curve fitting and statistical analyses for in vitro experiments were performed using GraphPad Prism version 4. Acknowledgments The authors would like to thank Ms. References 1.

There is considerable inter-and intra-batch variability in smoking mixtures, both in terms of substances present and their quantity.

Thus, there is a higher potential for overdose than with cannabis. Initially, JWH and JWH were the two most common synthetic cannabinoid chemicals found in a variety of herbal smoking blends. Reportedly offering a high 4 times stronger than marijuana, these compounds are commonly associated with herbal smoke and incense products sold under names such as K2, K3 Legal, Spice, Syn, Haze, Cloud Nine, Serenity and many others.

Synthetic cannabinoid chemicals are often laced in the herbal smoking products that are readily available via the Internet and in many head- shops around the country. Users looking for a high often turn to these herbal smoking or incense products because they do not show up on a standard urine drug test. Users smoke the product by rolling joints, smoking it in pipes, or inhaling fumes via vaporizers.

Users also report that herbal blends or pure chemical concoctions can be ingested with an infusion or solvent process; purportedly allowing them to manage the potency and dose of the active ingredient s.

Users indicate the high comes on slow at first, then with surprising potency. There have been many reports about the adverse effects including agitation, rapid heart rate, confusion, dizziness and nausea.

In July , the DEA banned synthetic cannabinoids based on their structural classification, explicitly naming 15 chemicals, citing numerous calls to poison control centers around the nation. Routinely, the DEA bans newer compounds after they have caused multiple overdoses. However, newer generation compounds continually emerge—making it more vital than ever to target synthetic marijuana.

Immunoassay screens are now available for some synthetic cannabinoids. The method relies on monitoring multiple metabolites for each drug.
