No such ingredient is found in salt blocks for cattle. It is merely a myth or rumor that has been passed along from one drug addict to another in their attempt to gain different ingredients to make methamphetamine.
They are not and never have been. Ephedrine is not found in medicated salt blocks.
Salt is sodium chloride, and because salt is this chemical compound, this is the main reason why it is used so frequently as a source of sodium AND chloride for livestock like horses and cattle.

Safe-Guard makes a medicated dewormer salt block, and Bovatec makes a medicated block made to increase average daily gain of pasture stocker, slaughter, feeder cattle and beef/dairy replacement heifers. However, no other manufacturer makes any type of medicated salt block that contains the mythical ephedrine that is claimed to be extracted and used for crystal meth.

This has been answered before and the answer is no.
Epheridrine is only used when recommended by a medical doctor.
None and no such block exists. Ephedrine is a chemical that makes animals (and people) feel happy because it initiates dopamine in the brain. There is no disease that can be treated by this chemical, especially in livestock.
