Objective:
To report a case of a 22-year-old man who developed neuropsychiatric symptoms after chronic use of tiletamine-containing e-cigarettes.
Approach:
Key Findings:
- The patient experienced progressive neuropsychiatric symptoms after chronic use of tiletamine-containing e-cigarettes.
- Symptoms included gait instability, dysarthria, hand tremor, emotional instability, and marked craving.
- Brain MRI and electromyography showed no structural abnormalities, while electroencephalography suggested functional brain involvement.
- Symptoms improved after discontinuation of tiletamine use and treatment.
Interpretation:
Chronic tiletamine abuse via e-cigarettes may lead to persistent neuropsychiatric dysfunction and dependence-related features.
Limitations:
- The actual chemical composition of the e-cigarette cartridges was not analytically confirmed.
- No toxicological screening for tiletamine or other substances was performed at presentation.
Conclusion:
This case suggests that chronic use of tiletamine-containing e-cigarettes can result in significant and lasting neuropsychiatric impairment.
