Ketamine addiction following a single sub-anaesthetic ketamine treatment for acute suicidality in a psychiatrically multimorbid patient: case report.
Single intranasal ketamine dose triggered addiction cascade in a multimorbid patient with prior substance use history.
This case demonstrates that even single ketamine exposures can trigger addiction in vulnerable individuals. The patient’s complex psychiatric history and prior substance use may have predisposed her to seeking illicit ketamine to self-medicate intrusive thoughts.
As ketamine becomes more widely used for treatment-resistant depression and suicidal ideation, clinicians need frameworks for identifying patients at higher addiction risk. This case suggests that psychiatric complexity and substance use history warrant heightened caution.
| Study Type | Case Report |
| Population | 25-year-old woman with depression, OCD, autism spectrum disorder, anorexia nervosa, and prior alcohol/cannabis use |
| Intervention | Single sub-anesthetic intranasal racemic ketamine dose for acute suicidality |
| Comparator | Not applicable |
| Primary Outcome | Development of ketamine addiction and subsequent polysubstance abuse |
| Key Finding | Patient developed daily ketamine use within weeks, progressing to cocaine and 3-MMC abuse with significant functional deterioration |

Single ketamine doses can precipitate addiction in susceptible patients with complex psychiatric presentations and substance use histories. Risk assessment and monitoring protocols should account for this vulnerability, particularly when patients report subjective benefits that might drive seeking behavior.
This single case cannot establish causation or predict which patients will develop addiction after ketamine exposure. It provides no data on addiction rates in broader populations or effective prevention strategies.
Case reports cannot establish general risk patterns or mechanisms. The patient’s complex psychiatric presentation makes it difficult to isolate ketamine’s role versus underlying vulnerability factors in the addiction development.
While ketamine addiction after single doses appears uncommon, this case highlights the need for careful patient selection and post-treatment monitoring. Complex psychiatric presentations with substance use history may represent higher-risk populations requiring enhanced safeguards.

FAQ
Can a single dose of ketamine trigger addiction in psychiatric patients?
Yes, this case demonstrates that even one sub-anesthetic dose of intranasal ketamine can trigger addiction in vulnerable patients. The 25-year-old patient developed compulsive ketamine-seeking behavior after experiencing transient symptom relief from a single controlled dose.
Which patients may be at highest risk for ketamine addiction after clinical use?
Patients with multiple psychiatric comorbidities and prior substance use history appear to be at elevated risk. This case involved a patient with depression, OCD, autism spectrum disorder, anorexia nervosa, and previous sporadic alcohol and cannabis use.
What are the warning signs of ketamine addiction following clinical treatment?
Key warning signs include seeking illicit ketamine to recreate therapeutic effects, escalation to daily use within weeks, and severe psychosocial consequences like financial distress and housing instability. Patients may also expand to other substances like cocaine as seen in this case.
How should clinicians monitor patients after ketamine treatment for suicidality?
Close follow-up is essential to assess for substance-seeking behaviors and monitor for escalation of use patterns. Clinicians should be particularly vigilant with patients who have psychiatric comorbidities and substance use history, implementing structured addiction risk assessments.
What are the clinical implications for ketamine protocols in psychiatric settings?
This case suggests the need for enhanced screening protocols and risk stratification before ketamine administration. Clinical protocols should include comprehensive addiction risk assessment and robust post-treatment monitoring, especially for high-risk patient populations.
