I guess there isnt any, but in my experience, there is no noticable difference from different blends of changa and pure DMT, atleast not to me, unless there is salvia divinorum in the changa, which there often is, people cut their changa with salvia and pass it off as the real thing, atleast here in scandinavia, when i get that type of blend there is a major difference, but from one herbal mix to another its more or less the same, to the degree dmt trips can be the same

Copper cookware. Pots and pans made from 100% copper fall into a slightly different category. Even though it is also a metal on the ATSDR priority toxin list just like aluminum, copper is an essential mineral that is currently deficient in many U.S. diets. Its essential nutrient status makes it different from aluminum, and some people include it as a desirable cookware material for this reason.
