- According to reports from the CDC, an increasing number of calls to poison centers for synthetic cannabinoid exposure has been noted on a local as well as national level
- A report in the Morbidity and Morality Weekly (MMWR) published June 2015 cites a 330% increase monthly incidence nationwide from January 2015 to April 2015
- A report in the MMWR published April 2015 cites 721 suspected cases including 9 deaths at the Mississippi Control Center from April 2 to May 3
- Most commonly reported adverse effects
- Tachycardia, hypertension, violent and aggressive behavior, confusion, a mixture of agitation/aggression/and decreased mental status
- Presentation of a case report of a 10-month-old female requiring intubation for severely depressed mental status after exposure to AB-PINACA, a synthetic cannabinoid
- Presentation of a pediatric case series of 8 patients aged 15-18 years old with concern for myocardial ischemia after exposure to synthetic cannabinoids, on the basis of EKG changes and/or elevated troponin
- Cardiovascular effects of synthetic cannabinoids are mediated through CB1, and CB2 receptors
- EKG changes ranged from: ST changes and TWI in a coronary distribution, bradycardia, tachycardia, LVH, ST or T wave flattening
- 2/8 patients had positive troponins at .16, and .39 ng/ml
- 6/8 patients had echocardiograms done which were completely normal
- Presentation of a case report of a 22-year-old man and his dog, both of whom seized after exposure to novel synthetic cannabinoid, ‘Crazy Monkey’
- The dog owner admitted smoking 3 pots of ‘crazy monkey’ for several weeks
- Both man and dog tested positive for PB-22 (QUIPIC)
Q: What was the first paper to establish the effectiveness of hemodialysis in removing salicylates in the animal model?
