Popular Nicotine Pouches Linked to Seizure Risk and Brain Damage: Inhaled CBD Shows Promising Protective Effects
New study published in Nicotine and Tobacco Research (Oxford University Press) provides first experimental evidence linking oral nicotine pouch use to seizure vulnerability, glymphatic disruption, and neuroinflammation
AUGUSTA, GA, March 27, 2026 -- A new study published in Nicotine and Tobacco Research (Oxford University Press) provides the first experimental evidence that chronic oral nicotine pouch exposure significantly increases seizure susceptibility, disrupts the brain's glymphatic waste-clearance system, and triggers dangerous neuroinflammatory responses — while inhaled CBD reverses all these effects.
The research was conducted by Dr. Babak Baban (immunologist) and Dr. Lei Phillip Wang (neuroscientist), co-founders of Medicinal Cannabis of Georgia LLC, a research company located at Augusta University's BioBusiness Incubator.
Key Findings
Nicotine pouches have surged in popularity as "safer" smokeless alternatives, yet their neurological consequences remain poorly understood. This study used commercially available ZYN nicotine pouches (Philip Morris International) under approved institutional protocols to investigate these potential risks. The research reveals a dangerous biphasic pattern:
• Short-term exposure: Transiently reduced seizure severity
• Chronic exposure (7 days): Nearly doubled seizure severity, impaired brain glymphatic function, elevated key inflammatory markers (IL-6, HMGB1), and amplified neuronal activation markers (BDNF, c-FOS)
"Our findings suggest the neurological risks of these products may be far more significant than currently appreciated," said Dr. Baban.
A First-Ever Discovery: Nicotine Pouches and Brain Waste Clearance
This is the first study to link oral nicotine pouch use to impaired glymphatic function — the brain's critical system for clearing toxic waste during sleep. When this system fails, it creates conditions that favor neuroinflammation, neurodegeneration, and increased seizure vulnerability.
"When the glymphatic system is disrupted, it creates conditions that favor neuroinflammation and neurodegeneration," noted Dr. Wang.
Inhaled CBD Reverses All Pathological Effects
Remarkably, a single inhalation of broad-spectrum CBD reversed all nicotine-induced damage — restoring seizure thresholds, normalizing inflammation, and reestablishing glymphatic function. Mechanistic studies confirmed CBD suppresses neuroinflammation through multiple pathways, acting as a global homeostatic regulator rather than targeting a single target.
"CBD isn't just blocking one pathway — it's rebalancing an entire disrupted neurobiological network," said Dr. Wang.
Public Health Implications
These findings challenge the perception of nicotine pouches as neurologically safe, particularly for individuals at elevated seizure risk — including epilepsy patients, chronic nicotine users, and young adults. The researchers call for urgent clinical investigation and greater regulatory scrutiny of these rapidly growing products.
