I'm referring to a single 1cm^2 paper tab; of course the contents can vary due to the unregulated effects of prohibition. This is just not enough to induce strong visual hallucinations and Hunter S. Thompson type experiences. There has also been a recent interest in micro-dosing (https://www.nytimes.com/2017/01/07/style/microdosing-lsd-aye...) though this seems extremely difficult to procure in ways that I'd trust, I keep my eyes open.
