MINI CASE IN PSYCHOACTIVE DRUGS AND THEIR EFFECTS ON THE BRAINCase 1:1.I believe Jenn has been taking ecstasy (methylenedioxymethamphetamine) because she has an altered perception of time and is experiencing hallucinations. 2.Subjective effects of the drug are hallucinations, sweating, teeth clenching, elevated heart rate, distorted perception of time and increased sociability. 3.Ecstasy acts as both a stimulant and a hallucinogen because of its molecular structure, which is similar to that of both amphetamines and LSD. Similar to amphetamines and cocaine, ecstasy blocks the reuptake pumps for certain neurotransmitters, thus increasing their levels in the synaptic gap and their effect on the postsynaptic neurons’ receptors. Ecstasy increases the release of serotonin by the serotonergic neurons. The individual will then experience increased energy, euphoria, and the feeling of being different from other individuals. A few hours later, serotonin levels decrease. This is due to the reduced activity of tryptophan hydroxylase, the enzyme responsible for synthesizing serotonin. This decrease can last much longer than the initial increase. An artificial increase in the level of a neurotransmitter creates a negative response on the enzyme that produces it. As a result, when intake of the drug is discontinued, the excess
