> I’ve been tapping my foot ferociously since I was a kid and the most I’ve been “on” is caffeine. Lots of it, though
So you're kind of proving the parent poster's point, no?
Or are you suggesting caffeine is not stimulant or a psychoactive drug?

Also, the foot tapping behavior can be related to caffeine consumption even if you also do it when not taking caffeine. Some people (like me) metabolize caffeine a lot slower than average, so its effects last a lot longer (twice longer or so, I think). Also, caffeine notably causes sleep disruption. And caffeine withdrawal can also cause irritability.
Caffeine can also increase anxiety or anxiety-related behaviors, and even if anxiety or these behaviors are not exclusively experienced while taking caffeine, it can still increase the likelihood and magnitude of its effects. These behaviors can also persist in the absence of substance intake for a variety of (psychological) reasons.
A typical cup of coffee contains about the same proportion of caffeine compared to a lethal caffeine dose than the proportion of one Aderall dosage compared to a lethal amphetamine dose.
How about that?
It's a decent measure for how much a certain amount of a drug is likely to cause immediate important effects in the body.
LSD does cause significant psychoactive effects with one thousandth of that amount, which suggests that for a typical isolated dose, LSD is safer than caffeine and amphetamines. Not to mention that LSD is not as addictive.
But I don't think that invalidates my underlying point regarding caffeine, even if the lethal dose is not a perfect measure.
Of course there is, and it's obviously a positive correlation.
I think you just proved you don't understand what a correlation is...

Toxicity and psychoactivity are completely independent from one another. If you can’t understand that there’s not much else I can say to you.
