I have some good earth tea. Its ingredients known to help lucid dreams are Rose Hips, Chamomile, Cinamon, Peppermint, and Anise. I looked up all the other ingredients, and they appear to be completely non-toxic.

Would smoking it be more or less effective than drinking it? I know all smoke contains carbon monoxide, fine particles, and some carconogens, but it might be more enjoyable to smoke it than drink it.
