This case series represents the first reported use of stellate ganglion block (SGB) for cannabis use disorder, introducing a potential procedural intervention for a condition with limited evidence-based treatments. The sympathetic nervous system modulation achieved through SGB could theoretically address both withdrawal symptoms and underlying neurobiological aspects of cannabis dependence.
The case series describes stellate ganglion block procedures performed on patients with cannabis use disorder, targeting the sympathetic ganglia in the neck region. SGB has established uses in treating PTSD, chronic pain, and autonomic dysfunction by temporarily blocking sympathetic nerve transmission. The authors report improvements in cannabis use patterns following the procedure, though the mechanism by which SGB might influence cannabis dependence remains unclear. This represents preliminary observational data rather than controlled clinical evidence.
“While intriguing, a case series of an invasive procedure for cannabis use disorder raises more questions than it answers about efficacy, safety, and appropriate patient selection. We need randomized controlled data before considering SGB as a legitimate treatment option for cannabis dependence.”

FAQ
What is a stellate ganglion block?
A stellate ganglion block is an interventional procedure that involves injecting anesthetic near the stellate ganglion, a collection of nerves in the neck. This procedure is typically used to treat various pain conditions and potentially other neurological symptoms.
How might stellate ganglion block help with cannabis use disorder?
The stellate ganglion block may help modulate the sympathetic nervous system, which could potentially affect addiction pathways and withdrawal symptoms. This represents an emerging treatment approach that requires further clinical investigation.
What is cannabis use disorder?
Cannabis use disorder is a condition where cannabis use causes significant impairment or distress in a person’s daily life. It involves continued use despite negative consequences and can include tolerance, withdrawal symptoms, and inability to control use.
Is this treatment approach proven effective?
This appears to be an emerging finding that warrants close monitoring rather than an established treatment. More research and clinical trials would be needed to determine the safety and efficacy of this approach for cannabis use disorder.
Who would be qualified to perform this procedure?
Stellate ganglion blocks should only be performed by qualified medical professionals, typically anesthesiologists or pain management specialists with specific training in interventional procedures. The procedure requires precise anatomical knowledge and proper sterile technique.
