Paradoxical increase in synthetic cannabinoid emergency-related presentations after a citywide ban: Lessons from Houston, Texas.

Image result for Bull Menninger Clin

“Synthetic cannabinoids (SCs) have become a major drug of abuse associated with severe hospital presentations. There have been a variety of legislative efforts to regulate these drugs: The authors focus on trends in SC-related hospitalizations at Ben Taub General Hospital before and after a ban enacted by the city of Houston.

Data from all consults seen by Ben Taub’s Licensed Chemical Dependency Counselor were examined for changes in SC-related presentations before and after the ban. The findings were compared alongside other reports of current SC use.

A significant increase was found in the prevalence of SC-related presentations at Ben Taub Hospital following Houston’s citywide ban. These findings are consistent with other state and national data.

Houston’s ordinance was expected to decrease harmful effects of SC in the community; however, the data suggest an increase in presentations since the legislation was passed.

While further study is needed, it initially appears that the threat of SCs is still considerable despite policy efforts. These results suggest the need for further monitoring of SC use and continued collaboration toward effective public health measures.”

Synthetic and Patented Cannabinoids

“Historically, laboratory synthesis of cannabinoids were often based on the structure of herbal cannabinoids, and a large number of analogs have been produced and tested, especially in a group led by Roger Adams as early as 1941 and later in a group led by Raphael Mechoulam.

Newer compounds are no longer related to natural cannabinoids or are based on the structure of the endogenous cannabinoids.

Synthetic cannabinoids are particularly useful in experiments to determine the relationship between the structure and activity of cannabinoid compounds, by making systematic, incremental modifications of cannabinoid molecules.

Medications containing natural or synthetic cannabinoids or cannabinoid analogs:

  • Dronabinol (Marinol), is Δ9-tetrahydrocannabinol (THC), used as an appetite stimulant, anti-emetic, and analgesic
  • Nabilone (Cesamet), a synthetic cannabinoid and an analog of Marinol. It is Schedule II unlike Marinol, which is Schedule III
  • Sativex, a cannabinoid extract oral spray containing THC, CBD, and other cannabinoids used for neuropathic pain and spasticity in Canada and Spain. Sativex develops whole-plant cannabinoid medicines
  • Rimonabant (SR141716), a selective cannabinoid (CB1) receptor antagonist used as an anti-obesity drug under the proprietary name Acomplia. It is also used for smoking cessation

Other notable synthetic cannabinoids include:

  • CP-55940, produced in 1974, this synthetic cannabinoid receptor agonist is many times more potent than THC
  • Dimethylheptylpyran
  • HU-210, about 100 times as potent as THC
  • HU-331 a potential anti-cancer drug derived from cannabidiol that specifically inhibits topoisomerase II.
  • SR144528, a CB2 receptor antagonists
  • WIN 55, a potent cannabinoid receptor agonist
  • JWH-133, a potent selective CB2 receptor agonist
  • Levonantradol (Nantrodolum), an anti-emetic and analgesic but not currently in use in medicine”
