Immersed this spring in research for this chapter, I was sorely tempted to plant one of the hybrid cannabis seeds I'd seen for sale in Amsterdam. I immediately thought better of it, however. So I planted lots of opium poppies instead. I hasten to add that I've no plans to do anything with my poppies except admire them - first their fleeting tissue-paper blooms, then their swelling blue-green seedpods, fat with milky alkaloid. (Unless, of course, simply walking among the poppies is enough to have an effect, as it was for Dorothy in Oz.)
