para-Chloromethamphetamine (also known as 4-Chloromethamphetamine and 4-CMA) is a stimulant that is the N-methyl derivative and prodrug of the neurotoxic drug para-Chloroamphetamine. It has been found to decrease serotonin in rats. Further investigation into the long-term effects of chloroamphetamines discovered that administration of 4-CMA caused a prolonged reduction in the levels of 5-HT and the activity of tryptophan hydroxylase in the brain one month after injection of a single dose of the drug.
Another study on rats found that 4-Chloromethamphetamine was more potent at inducing conditioned taste aversion than methamphetamine.
4-Chloromethamphetamine was further investigated in the 1960s along with 4-CA and it was noted that they differed from their parent amphetamine and methamphetamine substances by exhibiting only a slight central stimulant effect in both animals and humans and that they acted like antidepressants rather than stimulants.
