A non-neurotoxic version of MDMA that you could take every day like coffee would represent, not only a watershed moment for *human wellbeing*, but also, perhaps less intuitively, it would entail a breakthrough in *human coordination*.

Just consume reversible MAOIs (eg P. harmala seeds -> harmala alkaloids); they prevent oxidation of monoamines (serotonin being one) resulting in the natural amounts of them already in your organism being bioavailable longer and more potently
They are neurogenic:

Potential mild and indirect neurotoxic properties of harmine seem to derive from inhibition of acetylcholinesterase; nowhere near comparable to the direct neurotoxicity of MDMA:
