Synthetic cannabinoids cause severe toxicity including heart damage and death, unlike natural cannabis
Synthetic cannabinoid receptor agonists, the most commonly abused new psychoactive substances, act as full receptor agonists and cause severe toxicity including cardiotoxicity, immunotoxicity, and death, unlike natural THC.
Quick Facts
What This Study Found
SCRAs are the most commonly abused new psychoactive substances worldwide. Unlike natural THC (a partial agonist), most SCRAs are full CB1 and CB2 agonists, producing much greater effects. Associated toxicities include cardiotoxicity, immunotoxicity, and death.
Key Numbers
NPS classified into six groups; SCRAs are the largest class; sold as herbal incense, bath salts, legal highs; some classified as Schedule 1 in the US
How They Did This
Review of the general pharmacological characteristics, recent findings, and adverse effects of synthetic cannabinoid receptor agonists, focusing on their mechanism of action and clinical toxicity.
Why This Research Matters
The fundamental pharmacological difference between natural cannabis (partial agonist) and synthetic cannabinoids (full agonists) explains why synthetics are so much more dangerous and why natural cannabis safety data cannot be applied to them.
The Bigger Picture
Understanding the pharmacological basis for synthetic cannabinoid toxicity is essential for emergency physicians and for public messaging that distinguishes these products from natural cannabis.
What This Study Doesn't Tell Us
Rapidly evolving landscape of new compounds makes any review potentially outdated. Clinical data is primarily from case reports and poison control data rather than systematic studies.
Questions This Raises
- ?Can emergency departments reliably detect synthetic cannabinoids?
- ?Would wider access to natural cannabis reduce synthetic cannabinoid use?
- ?Are there effective treatments for acute synthetic cannabinoid toxicity?

What do these levels mean? →Frequently Asked Questions
Why are synthetic cannabinoids more dangerous than natural cannabis?
Natural THC is a partial agonist at cannabinoid receptors, meaning it only partially activates them. Synthetic cannabinoids are full agonists, maximally activating the receptors and causing much more severe effects including organ toxicity and death.
What are the health risks of synthetic cannabinoids?
Documented toxicities include cardiotoxicity (heart damage), immunotoxicity (immune system damage), and death. These effects are not seen with natural cannabis at typical doses because of the fundamental pharmacological difference.
