How does Ecstasy affect the human brain?
So, the easiest way to think about it is that it really floods the brain with serotonin. Now, serotonin is a neurotransmitter that is involved in feeling good, having less anxiety, and having a feeling of satiety like you don't really need anything. Everything that you need, you have. If you want to get into a more complicated level, it blocks the reuptake of serotonin the same way that the prescription anti-depressants do. So, since there's less recycling there's more available in the synapse to go across. But also, not only does it block the recycling, but it just floods the synapse with serotonin and to a lesser extent dopamine and other chemicals involved, but it really is a primarily serotonergic affect. The increased serotonin is what makes you feel so good.
