Serotonin is the hormone what makes us happy, so why aren’t we just injecting it into our body/taking it as tablets to get out of misery on command?
In: Biology
Because our neurotransmitters metabolize into neurotoxic agents, an excess results in long-term brain damage. Ie, methamphetamine, and MDMA, these drugs aren’t inherently neurotoxic but the toxicity from their use come from more neurotransmitter metabolites which are charged and destroy cell walls killing brain cells.
