This is a market in a series on markets for possible quantified self experiments I could run.
Context here, in short: I will put up >10 of these markets, run the "best" one, and a random one (resolving them to the outcome), and will resolve all the others as N/A. In all experiments, I will be using the statistical method detailed here, code for it here.
40 samples, with blocking after waking up, 20 intervention with 2mg nicotine, 20 placebo (similar-looking square chewing gum). Expected duration of trial: ~4½ months (two samples/week, to avoid getting addicted to nicotine).
In general, by meditative absorption I mean the concentration/tranquility (in Buddhist terms samatha) during a ≥30 minute meditation session in the morning, ~45 minutes after waking up and taking the substance (less if the substance starts working immediately). I will be doing at least 15 minutes of anapanasati during that meditation session, but might start (or end) with another practice).
Past meditation data can be found here.

1.00@DanMan314 I wanted to keep an option open to maybe add more detailed negative options later. (Now that I think of it that's nonsensical and I won't do it on the other markets).
@NiplavYushtun I see, but wouldn't that contradict Cohen's d of d<0? If I were to bet on it now I would be assuming it covers the full range from -inf to 0.
