I think the point of the micro-dose is that it's not enough to make you feel high, just enough to have positive effects. So it's likely not the same effect you've experienced, unless you've experimented with micro-doses.
10µg and 100µg are very different. You don't trip from 10µg as you would from 100µg.
You may feel a little bit more energetic, a little bit happier, conversations flow better etc... But it's all very subtle.
From the article: > In fact, a common problem for new experimenters, according to Fadiman, is that people are used to feeling the effects of drugs, and a micro-dose of LSD can sometimes be less perceptible than a cup of coffee.
