Psychosis in a Military Veteran in the Context of Hallucinogen Use: A Case Report.
Cureus February 19, 2025 Paria Parhami, Sydney E Moriarty, Jay Parikh et al.
A 60-year-old female veteran with chronic PTSD and no prior psychiatric hospitalizations developed persistent delusions of parasitic infestation after 18 months of recreational intravenous DMT use. Her delusions that worms were coming out of her skin persisted despite haloperidol treatment but improved after 15 days of hospitalization following substance clearance and psychoeducation. The timing of hallucinogen use and symptom onset was not fully consistent, raising concern for a primary delusional disorder exacerbated by substance use. This novel case suggests a potential link between prolonged DMT use and delusional parasitosis, highlighting the need for further research.
