Hallucinogen persisting perception disorder (HPPD) is characterized by a continual presence of visual disturbances that are reminiscent of those generated by the ingestion of halucinogenic substances. Previous use of halucinogens is a necessary, though not sufficient, cause for the disorder. HPPD is distinct from flashbacks by reason of its relative permanence; whereas the latter is transient, the effects of HPPD occur without cesation for a prolonged, if not indefinite, period.

Can hallucinogen induced HPPD improve vision?

While the meaning of "improve" is ambiguous, HPPD causes distortions in vision that are typically distracting and bothersome. Thus, HPPD does not improve vision in any traditional sense of the word.

What is An unexpected recurrence of the effects of drugs?

A transient recurrence of a drug's effects after it has left one's system is known as a flashback. While the frequency and causes of flashbacks are debated, they most commonly occur after the ingestion of hallucinogens, such as LSD and psilocybin. A prolonged, continuous presence of a hallucinogen's effects (mainly visual) is called HPPD, Hallucinogen Persisting Perception Disorder. Unlike with flashbacks, those suffering from HPPD experience constant perceptual disturbances.

What happens to someone who continue to eat magic mushrooms?

It depends on the person and how often they trip, etc. Nothing significant physically. If the person is abusing them it could probably affect them negatively mentally. If the person is respecting the mushrooms then you might see positive change in the way they act. I know that some people who trip often have something HPPD like (ie "flashbacks") when they smoke. If they're doing it weekly or less, it won't be that big of a deal...

Acid trip never ending?

A trip generally lasts for about 12 hours. Subjective time dilation could make it seem much longer, however. In the physical world, however, it will end. (Unless you make the argument that life itself is a sort of acid trip... Or if you have schizophrenia.)


Which is a likely resulting of taking LSD?

If taking a dose of LSD above 50 mcg effects will be felt. These effects range from positive, such as a sense of enlightenment, appreciation of colors and music, to negative, such as jaw clenching and panic attacks. If taking a ridiculously high dose HPPD can be developed (but since you're asking this question I wouldn't consider it). Long term effects are close to none except the memory of the experience (whether positive or negative). For a very small percentage of users the experience can have long lasting mental effects (<1%) such as flash backs or uncovering mental illnesses.

Can you get a disease from magic mushrooms?

If improperly stored, fungus can grow in magics mushrooms (mushrooms themselves are a speciece(sp?) of fungus). However, magic mushrooms themselves do not cause any diseases, any other than getting a food infection from fungi that can grow on improperly stored magic mushrooms (which can also happen to normal mushrooms or any other type of fresh food).
