Are shrooms and LSD the same?

No, they are completely different substances.

LSD's main effect is hallucinations.

While PCP does cause hallucinations and is also classified as a hallucinogen, it is also a dissociative and can cause extreme behavior changes.

Here are some negative effects of PCP.

* Disturbing hallucinations and/or delusions * Severe anxiety, paranoia * Severe dissociation, depersonalization * Ataxia (loss of motor coordination) * Severe confusion, disorganized thinking * Psychotic episodes * Physical aggression * Nausea, vomiting * Temporary amnesia * Severe distortion or loss of auditory/visual perception * Decreased heart rate, blood pressure, and respiration (high doses) * Seizures (high doses) * Hangover including dizziness, numbness and lethargy; may last 24 hours or more * Coma (high doses, increased risk when combined with depressants) * Possible neurotoxicity (controversial)
