Changa

Changa (or Xanga) is a blanket term to describe any of many smokable blends that contain DMT (usually with an MAOI or RIMA).

Changa is usually made by blending together any combination of desired smokable herbs and pouring a solvent (like Isopropyl Alcohol) containing DMT and an MAOI over the chosen blend of herbs, letting the mixture dry completely and then smoking the final product. Although there are many varieties of changa, like ayahuasca, the key active ingredients are consistently DMT and an MAOI. The inclusion of the MAOI typically serves to extend the experience by 10-30+ minutes and can render it more coherent and less amnesic than through pure vaporization.

The percentages of DMT and MAOI concentration in the mixture are variable. A typical mixture would be characterized by breakthrough experiences at a dosage of approximately "one full bong bowl, with each breath held in for at least 20 seconds". There have also been reports of breakthroughs occurring with changa that has been rolled into joints, though this is a far less reliable method of doing do.

"Enhanced leaf" is sometimes used to describe DMT-herb mixtures that do not contain MAOIs. Common herbs that can be used for this purpose can range anywhere from passionflower to mint leaves.

Dangerous interactions

Warning: Many psychoactive substances that are reasonably safe to use on their own can suddenly become dangerous and even life-threatening when combined with certain other substances. The following list provides some known dangerous interactions (although it is not guaranteed to include all of them).

Always conduct independent research (e.g. Google, DuckDuckGo, PubMed) to ensure that a combination of two or more substances is safe to consume. Some of the listed interactions have been sourced from TripSit.

• "[[DangerousInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] & "[[DangerousInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - 25x compounds are highly stimulating and physically straining. Combinations with Changa should be strictly avoided due to the risk of excessive stimulation and heart strain. This can result in increased blood pressure, vasoconstriction, panic attacks, thought loops, seizures, and heart failure in extreme cases.
• "[[UncertainInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Combining alcohol with stimulants can be dangerous due to the risk of accidental over-intoxication. Stimulants mask alcohol's depressant effects, which is what most people use to assess their degree of intoxication. Once the stimulant wears off, the depressant effects will be left unopposed, which can result in blackouts and severe respiratory depression. If mixing, the user should strictly limit themselves to only drinking a certain amount of alcohol per hour.
• "[[UnsafeInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Combinations with DXM should be avoided due to its inhibiting effects on serotonin and norepinephrine reuptake. There is an increased risk of panic attacks and hypertensive crisis, or serotonin syndrome with serotonin releasers (MDMA, methylone, mephedrone, etc.). Monitor blood pressure carefully and avoid strenuous physical activity.

• "[[UncertainInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Some reports suggest combinations with MXE may dangerously increase blood pressure and increase the risk of mania and psychosis.
• "[[UncertainInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Both classes carry a risk of delusions, mania and psychosis, and these risk may be multiplied when combined.
• "[[UnsafeInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Changa may be dangerous to combine with other stimulants like cocaine as they can increase one's heart rate and blood pressure to dangerous levels.
• "[[DangerousInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Tramadol is known to lower the seizure threshold and combinations with stimulants may further increase this risk.
• "[[DangerousInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - This combination may increase the amount of neurotransmitters such as dopamine to dangerous or even fatal levels. Examples include syrian rue, banisteriopsis caapi, and some antidepressants.

Serotonin syndrome risk

Combinations with the following substances can cause dangerously high serotonin levels. Serotonin syndrome requires immediate medical attention and can be fatal if left untreated.

• MAOIs - Such as banisteriopsis caapi, syrian rue, phenelzine, selegiline, and moclobemide.
• Serotonin releasers - Such as MDMA, 4-FA, methamphetamine, methylone and αMT.
• SSRIs - Such as citalopram and sertraline
• [[Wikipedia:SNRIs|DangerousInteraction::SNRIs]] - Such as tramadol and venlafaxine
• 5-HTP

There is an increased risk of serotonin syndrome when changa (or more specifically, the MAOI component of it) is taken with many antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs).
