"Ahhh, and so the hallucinations take you on a trip?" she hazarded. "Interesting. Anyway, if you do to Ravnica, remember this: the best hallucinogens come from the Golgari, they've been breeding them for thousands of years. The Izzet have the best stimulants. For those that use their drugs a lot, it's pretty much a question whether the exhaustion or the heart attack gets them first. The Selesnya have the best tranquilizers, which makes such sense, the Simic have some good drugs, but nine times out of ten, they laced it with something to bring you back to the, and if you want the best narcotics...those on a different plane entirely. Vampires on Innistrad, can't be beat."
