An interesting and questionable article on mescaline.

The article devotes a couple paragraphs on the tendency to vomit after drinking the Bolivian torch or San Pedro cactus. The author fails to comment that in Peru, the San Pedro cactus is used in ceremony, only under the guidance of a shaman and for spiritual purposes. It is not at all common to vomit, though it is true it does not taste good.

The reckless use of these sacred plants, that indigenous cultures have used historically, continues to be problematic.
