Yes, except in Brave New World the drug they took ditracted them from what was heppening...psychedelics turn you inwards and force you to reflect on yourself. I don't see how they would possibly act like in Brave New World, they're too profound and difficult and frightening. Huxley wrote Brave New World early on in his life, but he wrote Island later on, after he'd experimented with Mescaline...and it offers a much more positive take on the possibilities of drug use in society.
