How can I make my small quantity of shrooms more effective?

Grind them up in a coffee grinder, put them in a mesh tea ball and make tea with them. Breaking them down like this helps to extract the psilocybin and makes it easier for your body to absorb it. Once you drink the tea don't forget to ingest the mushrooms because even though the tea helps extract the psilocybin there is still some left in the actual mushroom.
