Mescaline Mescaline is legal only for certain religious groups (such as the Native American Church) and in scientific and medical research. In 1990, the Supreme Court ruled that the state of Oregon could ban the use of mescaline in Native American religious ceremonies. The Religious Freedom Restoration Act (RFRA) in 1993 allowed the use of peyote in religious ceremony, but in 1997, the Supreme Court ruled that the RFRA is unconstitutional when applied against states. Many states, including the state of Utah, have legalized peyote usage with "sincere religious intent", or within a religious organization, regardless of race. While mescaline-containing cacti
Compound of five tetrahedra orbit space "I"/"T" (of order 60/12 = 5) is naturally identified with the 5 tetrahedra – the coset "gT" corresponds to which tetrahedron "g" sends the chosen tetrahedron to. This compound is unusual, in that the dual figure is the enantiomorph of the original. If the faces are twisted to the right, then the vertices are twisted to the left. When we dualise, the faces dualise to right-twisted vertices and the vertices dualise to left-twisted faces, giving the chiral twin. Figures with this property are extremely rare. Compound of five tetrahedra The compound of five tetrahedra is one of the
