> Tobacco (or nicotine) serves a purpose - it promotes calm focus. Hence the heavy use by philosophers and truck drivers. Nicotine actually protects the brain. Unfortunately, it does so at the expense of heart and arteries. (With or without smoke to damage lungs.)

A bit of a misconception there. I mean yea nicotein will "calm" you I suppose, but only because your on edge due to the nicotein addiction you developed. People who dont smoke just get sick and feel like they want to puke.. But people who smoke regularly really just return to their pre-addicted normal feeling when the smoke so defeats the purpose mostly.

> There is a tiny amount of nicotine in green tea (~12 micrograms / cup). I find this sufficient for my purposes, and avoids the risks associated with larger doses.

No where near 12 micrograms. You are about 20x over the actual concentration in a cup. At least for the typical 1 gram per cup of water ratio.

 I just checked for assays - results vary from 0.12 to 0.69 mcg.  So either I slipped a decimal, or the report I was reading slipped a decimai.  😳

It happens. The key is you checked yourself rather than doubling down on bad data as most people do :)
