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. A blood pressure of 120/80 is considered normal for an adult. A blood pressure of 90/60 or lower is considered hypotension and a blood pressure between 120/80 and 90/60 is considered .  Decreased blood pressure is most commonly induced under the influence of moderate dosages of GABAergic depressant compounds, such as benzodiazepines and barbiturates. However, it can also occur under the influence of vasodilating compounds such as poppers as well as certain psychedelics and stimulants in an unpredictable manner.
