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 has been used and cherished for around 9,000 years. Pots that are made of copper are ideal heat conductors; the material is durable, hygienic and corrosion-resistant. Above all, it is the excellent heat conductivity that makes copper a perfect base material for pots and pans.
We all know that copper is a good conductor of electricity and that is why it is used to make electric wires. Most of the electric appliances depend on copper wiring as it is cheaper as well as good conductor of electricity.n earlier days copper was used in making water proof roofing material. The copper carbonate and copper sulfate are highly resistant forms of corrosion. Copper as an alloy with nickel is used in ship building as it is corrosion resistant. Copper is used to protect the building from getting affected by lightning.
