This is a market in a series on markets for possible quantified self experiments I might run.

Context here, in short: I will put up >10 of these markets, run the "best" one (my own judgment, but probably just the one with the highest expected Cohen's d), 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.

50 samples in the morning, 25 intervention (4mg THC in oil, orally), and 25 placebo (whatever oil I can find that is closest in taste to the THC oil). Expected duration of the trial: ~2½ months (taken ~every day, with possible pauses).

However: I might not be able to run this market even if it looks good to run in expectation, because it turns out to be more difficult to get hold of THC oil than I expected, or potentially I'll have to go with a slightly different dose, or I'll have to vape it (and thus the placebo changes). I put 25% on not being able to run this experiment at all, and 65% on not being able to run it exactly as described.

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.
