This category of drugs includes LSD, mescaline and psilocybin mushrooms. They are known to alter a person’s state of perception and mood.

Mushrooms: Other Common Names: “shrooms”, “caps”, “magic mushrooms”

The main drugs found in shrooms are psilocybin and psilocin. There are many species of these mushrooms containing varying amounts of these drugs, as well as uncertain amounts of other chemicals. Mushrooms are typically taken orally often being eaten or brewed as tea.


There is often a feeling of nausea before the desired high, which is often mild and causes distorted feelings and perceptions. This includes hallucinations, altered perception of time, as well as impairment of motor functions. These effects begin within 20 minutes and can last up to 6 hours. “Flashbacks” which are reoccurrences of previous hallucinations can occur even after only one use.


Hallucinogen Persistent Perception Disorder (HPPD) more commonly known as “Flashbacks” are reoccurrences of previous hallucinations, and can occur even after only one use. Long term use can also result in persistent psychosis. The effects of mushrooms can be unpredictable and largely depends on the particular mushrooms used and the age and preservation of the extract. This can sometimes lead to a “Bad Trip” which can include terrifying thought distortions and intense feelings of anxiety, despair, death or losing control.

LSD (Acid)

LSD (d-lysergic acid diethylamide) comes in many forms. It is made in tablets, capsules, liquid, and on absorbent paper, and therefore is usually taken orally. It is one of the most potent mood changing chemicals, and is derived from a fungus that grows on grains.


After taking a dose of LSD the person typically experiences a “trip” which can last up to 12 hours. During these “trips” the person will experience unpredictable psychological effects including delusions and hallucinations. Most often a drug induced psychosis will be produced where users hear, see, and smell things that are not real. Most notable are the effects hallucinogens have on emotions which can shift rapidly from fear to euphoria and on the senses which are highly intensified.


Users of LSD may experience increased body temperature, heart rate, blood pressure, loss of appetite, nausea/vomiting, numbness and tremors, and sleeplessness. Respiratory failure or death due to careless or accidental behaviors can also occur. “Bad trips” and Hallucinogen Persistent Perception Disorder (HPPD) as seen in the hallucinogenic mushrooms may also occur.
