How did PCP users become associated with violent outbursts?

How did PCP users become associated with violent outbursts?

Answer: Most users do not report feeling violent, and in fact report feeling so uncoordinated that they cannot imagine starting a fight. Perhaps the association arises from the anesthetizing effects of PCP such that use of restraints and their associative discomfort, have little effect, and users might not feel pain. But this idea should be considered as no different from trying to restrain a person inebriated on alcohol.

What do studies indicate concerning MDMA's effects on brain cells?

What do studies indicate concerning MDMA's effects on brain cells?

Answer: Some studies show that large doses of MDMA given to laboratory animals can destroy serotonin neurons, but the relevance of this unclear.

What is "Suicide Tuesday" and how does it relate to the use of MDMA?

What is "Suicide Tuesday" and how does it relate to the use of MDMA?

Answer: Some users of MDMA report substantially negative mood states in the days immediately following its use. Some have speculated that initially MDMA causes a substantial release of serotonin, followed by a marked reduction of the neurotransmitter, lasting for several hours to days after the last dose. But there is little empirical evidence to support this position, so it is more likely that the depressed state relates to the lack of sleep and low blood sugar.
