Are there any damaging side effects to these types of drugs, such as LSD, mushrooms etc? For example with LSD assuming you get a good batch, don't mix it with anything else, and go on your trip in safe place, is there any damaging side effects long and short term.
"Hallucinogen Persisting Perception Disorder
[Categories: Psychiatric disorders, Hallucinogens]
Hallucinogen Persisting Perception Disorder (HPPD) is a condition that develops in some people after taking certain (A substance that is used as a medicine or narcotic) drugs. People with this condition experience perceptual (usually visual) distortions even after the "trip" is over and the drug and its (Any substance involved in metabolism (either as a product of metabolism or as necessary for metabolism)) metabolites have left the body. Under some definitions it is a requirement for diagnosis that the distortions affect the person's ability to function normally.
HPPD is different from a drug-induced psychosis in that a person with HPPD is fully aware that the distortions are not real (ie does not reflect any external reality that can be experienced by other people). Still, the distortions experienced by a person with HPPD can be powerful and may provoke (A vague unpleasant emotion that is experienced in anticipation of some (usually ill-defined) misfortune) anxiety. Some patients with HPPD are troubled with feelings of (The state of having committed an offense) guilt and regret.
Cases of HPPD can be divided in two categories: The cases in which the perceptual distortions are present all the time (sometimes even when the person in question has his/her eyes closed, in the case of visual distortions) and the cases where the person experiences the distortions in the form of " (A transition (in literary or theatrical works or films) to an earlier event or scene that interrupts the normal chronological development of the story) flashbacks" of short duration once in a while.
Most case reports seem to involve (A powerful hallucinogenic drug manufactured from lysergic acid) LSD or (A state of being carried away by overwhelming emotion) Ecstasy, perhaps reflecting the relative popularity of those drugs. In some cases the person in question took the drug(s) several times without problems, with the HPPD suddenly occurring after a particular timespan. In other cases, the person reports the condition worsening with repeated use of a drug. Sometimes the drug user may initially dismiss the symptoms as "after-effects" of the trip until realizing their persistent nature. Finally, in some cases HPPD occur after taking the drug just once or a few times. HPPD may occur some time after the drug experience - in some reports, even after several months.
The mechanism underlying HPPD is not known. The disorder seems to occur only in a minority of drug users. It is not known exactly what types of drug may cause it, or if the disorder is related to the presence of contaminants in the drugs taken."
