Datura (botany) Effects

A persistent, uncomfortable reduction in saliva production causing the mouth and throat to feel parched, sticky, and difficult to swallow through, commonly known as cottonmouth.

A noticeable acceleration of heartbeat that can range from a subtle awareness of one's pulse to a forceful, rapid pounding felt throughout the chest, neck, and temples. This effect is among the most commonly reported physiological responses to psychoactive substances and often accompanies stimulation, anxiety, or physical exertion during intoxication.

An abnormal physical intolerance and sensitivity to light that causes discomfort, squinting, or pain in the eyes, typically linked to substance-induced pupil dilation.

A visible enlargement of the pupil diameter (mydriasis) that can range from subtle widening to dramatic saucer-like expansion where the dark pupil dominates the iris. This effect is one of the most recognizable signs of psychedelic and stimulant intoxication and directly contributes to light sensitivity, enhanced color perception, and the characteristic "wide-eyed" appearance.

A dangerous slowing and shallowing of breathing that can progress from barely noticeable reductions in respiratory rate to life-threatening cessation of breathing. This is the primary mechanism of death in opioid overdoses and represents one of the most critical safety concerns across all of psychopharmacology.

Uncontrolled brain electrical activity causing convulsions and loss of consciousness -- a life-threatening medical emergency requiring immediate help.

An impairment of abstract thinking marked by a persistent inability to grasp or comprehend concepts and situations that would normally be perfectly understandable during sobriety.

Delirium is a serious and potentially dangerous state of acute mental confusion involving disorientation, incoherent thought, impaired attention, and frequently vivid hallucinations that the person cannot distinguish from reality. It represents one of the most medically concerning cognitive effects of substance use.

A persistent state of low mood, emotional numbness, hopelessness, and diminished interest or pleasure in activities, often occurring during comedowns, withdrawal, or as a prolonged after-effect of substance use.
