DMT (N,N-dimethyltryptamine) is a psychedelic substance that can temporarily alter perception, mood, thought and a person’s sense of reality. Effects are difficult to predict and depend on potency, amount, other substances, health, expectations and surroundings.
Possible effects and risks
Table of Contents
Reported effects can include intense visual or sensory changes, altered time perception, strong emotions, fear, panic, nausea, vomiting, increased heart rate and increased blood pressure. Impaired perception and judgment can contribute to falls, unsafe behavior or other injuries. Illicit products may contain an unexpected substance or contaminant.
DMT, mental health and medications
People with a personal or family history of psychosis or bipolar disorder should discuss psychedelic exposure with a qualified clinician. Interactions are not fully understood; tell emergency or treating clinicians about prescription medicines, supplements and other drugs used.
Addiction and treatment
Research cited by NIDA suggests classic psychedelics such as DMT are not typically strongly reinforcing, but a person can still experience harmful use or continue despite consequences. Assessment should focus on the actual pattern, impairment, co-occurring symptoms and safety rather than a label alone.
Frequently asked questions
