==Side effects==
===Psychological reactions===
DMT may trigger psychological reactions, known colloquially as a "[[bad trip]]", such as intense fear, paranoia, anxiety, [[panic attacks]], and [[substance-induced psychosis]], particularly in predisposed individuals.<ref name="pmid29366418" /><ref name="pmid28868040">{{cite journal | title = Novel Psychoactive Substances-Recent Progress on Neuropharmacological Mechanisms of Action for Selected Drugs | journal = Front Psychiatry | pmid = 28868040 | vauthors = Zurina H, Oliver B, Darshan S, Suresh N, Vicknasingam K, Erich S, Johannes K, Borid Q, and Christian M | doi = 10.3389/fpsyt.2017.00152 | date = 18 August 2017 | volume = 8 | page = 152 | pmc = 5563308 | doi-access = free }}</ref>{{better citation needed|reason=Both of these references refer to ayahuasca;  it's doubtful that DMT alone (smoked or by injection) actually lasts long enough for people with normal MAO levels to cause anything but brief fear at the worst due to the suddeness of the experience.  These things are also considered part of the ayahuasca experience among other side effects DMT doesn't have by some and either better references  are needed or this should be removed and kept on the ayahuasca article.|date=May 2025}}

===Addiction and dependence liability===
DMT, like other serotonergic psychedelics, is considered to be non-addictive with low abuse potential.<ref name="pmid8297217" />  A study examining [[substance use disorder]] for [[Diagnostic_and_Statistical_Manual_of_Mental_Disorders|DSM-IV]] reported that almost no hallucinogens produced dependence, unlike psychoactive drugs of other classes such as [[stimulants]] and [[depressant]]s.<ref name="pmid29366418">{{cite journal | journal = Current Neuropharmacology | volume = 17 | issue = 2 | pages = 1–15 | title = Ayahuasca: Psychological and Physiologic Effects, Pharmacology and Potential Uses in Addiction and Mental Illness | doi = 10.2174/1570159X16666180125095902 | issn = 1875-6190 | vauthors = Jonathan H, Jaime H, Serdar D, and Glen B | year = 2019 | url = https://www.eurekaselect.com/article/88194 | pmid = 29366418 | pmc = 6343205 | access-date = 2023-05-05 | archive-date = 2023-05-05 | archive-url = https://web.archive.org/web/20230505000155/https://www.eurekaselect.com/article/88194 | url-status = live }}</ref><ref>{{cite journal | journal = Society for the Study of Addiction | vauthors = Jon M, James L, and Erich L | date = September 1994 | title = The generalizability of the dependence syndrome across substances: an examination of some properties of the proposed DSM-IV dependence criteria | volume = 89 | issue = 9 | pages = 1105–1113 | doi = 10.1111/j.1360-0443.1994.tb02787.x | url = https://onlinelibrary.wiley.com/doi/10.1111/j.1360-0443.1994.tb02787.x | pmid = 7987187 | access-date = 2023-05-05 | archive-date = 2024-05-26 | archive-url = https://web.archive.org/web/20240526041617/https://onlinelibrary.wiley.com/doi/10.1111/j.1360-0443.1994.tb02787.x | url-status = live | url-access = subscription }}</ref> At present, there have been no studies that report [[Drug_withdrawal|drug withdrawal syndrome]] with termination of DMT, and dependence potential of DMT and the risk of sustained psychological disturbance may be minimal when used infrequently; however, the physiological dependence potential of DMT and ayahuasca has not yet been documented convincingly.<ref>{{cite journal | vauthors = Robert G | title = Risk assessment of ritual use of oral dimethyltryptamine (DMT) and harmala alkaloids | journal = Addiction | volume = 102 | issue = 1 | pages = 24–34 | date = January 2007 | pmid = 17207120 | doi = 10.1111/j.1360-0443.2006.01652.x | url = https://onlinelibrary.wiley.com/doi/10.1111/j.1360-0443.2006.01652.x | access-date = 2023-05-07 | archive-date = 2024-05-26 | archive-url = https://web.archive.org/web/20240526041617/https://onlinelibrary.wiley.com/doi/10.1111/j.1360-0443.2006.01652.x | url-status = live | url-access = subscription }}</ref>

===Long-term use===
There have been no serious adverse effects reported on long-term use of DMT, apart from acute cardiovascular events.<ref name="pmid28868040" /> Repeated and one-time administration of DMT produces marked changes in the cardiovascular system,<ref name="pmid28868040" /> with an increase in systolic and diastolic blood pressure; although the changes were not statistically significant, a robust trend towards significance was observed for systolic blood pressure at high doses.<ref name="pmid11292011">{{cite journal | title = Subjective effects and tolerability of the South American psychoactive beverage Ayahuasca in healthy volunteers | journal = Psychopharmacology | pmid = 11292011 | doi = 10.1007/s002130000606 | date = February 2001 | vauthors = Jordi R, Antoni F, Gloria U, Adelaida M, Rosa A, Maria M, James C, and Mandel B | volume = 154 | issue = 1 | url = https://link.springer.com/article/10.1007/s002130000606 | pages = 85–95 | s2cid = 5556065 | access-date = 2023-05-05 | archive-date = 2023-05-05 | archive-url = https://web.archive.org/web/20230505014511/https://link.springer.com/article/10.1007/s002130000606 | url-status = live | url-access = subscription }}</ref>
