Effect Categories - Cardiovascular Effects

Cardiovascular effects are defined as any uncomfortable physical effect that relates to the heart and blood vessels.

This page lists the various cardiovascular effects that can occur under the influence of certain psychoactive compounds.


  • Abnormal heartbeat

    An abnormal heartbeat is any of a group of conditions in which the electrical activity of the heart is irregular. During this state, the heartbeat may be too fast (over 100 beats per minute) or too slow (less than 60 beats per minute) and may be regular or irregular. An abnormal heartbeat is most commonly induced under the influence of moderate dosages of stimulant and depressant compounds, such as cocaine, methamphetamine, and GABAergics.

  • Decreased blood pressure

    Decreased blood pressure can be described as a condition in which the pressure in the systemic arteries is decreased to abnormal levels. It is most commonly induced under the influence of moderate dosages of GABAergic depressant compounds, such as benzodiazepines and barbiturates.

  • Decreased heart rate

    Decreased heart rate or bradycardia can be described as a heart rate that is lower than the normal heart rate at rest. It is most commonly induced under the influence of heavy dosages of depressant compounds, such as GABAergics, and opioids.

  • Increased blood pressure

    Increased blood pressure can be described as a condition in which the pressure in the systemic arteries is elevated to abnormal levels. It is most commonly induced under the influence of heavy dosages of vasoconstricting compounds, such as traditional stimulants and stimulating psychedelics.

  • Increased heart rate

    Increased heart rate or tachycardia is described as a heart rate that is faster than the normal heart rate at rest. It is most commonly induced under the influence of heavy dosages of stimulating compounds, such as traditional stimulants, certain psychedelics, and certain dissociatives.

  • Vasoconstriction

    Vasoconstriction can be described as a narrowing of the veins and blood vessels which results from a contraction of their muscular wall. It is most commonly induced under the influence of moderate dosages of stimulating psychedelic compounds, such as LSD, 2C-E, and DOC. However, it can also occur under the influence of traditional stimulants such as methamphetamine, caffeine, and MDMA.

  • Vasodilation

    Vasodilation can be described as a widening of the veins and blood vessels which results from the relaxation of smooth muscle cells within the vessel walls. It is most commonly induced under the influence of moderate dosages of cannabinoid compounds, such as cannabis, JWH-018, and THJ-018. However, it can also occur under the influence of poppers and viagra.
