Anxiety
Anxiety can be described as negative feelings of psychological tension and general unease. These feelings can range from subtle and ignorable to intense and overwhelming enough to trigger panic attacks and feelings of impending doom.
Anxiety can be caused by environmental factors, by an inescapable effect of the drug itself, due to a lack of experience with the substance, or by the experience of negative hallucinations.
Panic Attack
