1P-LSD is a functional analogue of LSD with comparable, though slightly weaker, effects. Crucially, while LSD is a Schedule I controlled substance in the US, 1P-LSD is unregulated and legal as a research chemical. All of the seltzer contained within Drink Me exists legally, but would become illegal at the moment of human consumption. Each can of 1P-LSD seltzer within the Drink Me refrigerator contains 3 ?g of 1P-LSD; Thirty-two cans of seltzer are roughly equivalent to a standard tab of LSD.
