No. This is a myth that has been passed along by drug addicts that have been trying to find unique ways of getting the necessary ingredients for illegal drugs like methamphetamine, also commonly known as crystal meth.
They are not and never have been. Ephedrine is not found in medicated salt blocks.
Nowhere. These type of blocks do not exist.
There are no salt or mineral nor medicated mineral blocks that contain any form of ephedrine in them. Sick animals are treated by antibiotics via injection, not by just giving them a "medicated" salt block.
None because no such block exists.
None. There is no such thing as a medicated salt block, especially one that contains ephedrine that you can use to make crystal meth!!
None. No salt licks, mineral blocks, medicated feed or any of that sort have ephedrine in them. This is a myth that has been tested and busted by various scientists that have tried to extract ephedrine from various animal-feed and chicken litter sources. Please see the related question below for more info.
Livestock salt blocks do not contain ephedrine. Ephedrine is a stimulant drug that is not suitable for use in livestock due to potential health risks and regulatory restrictions. It is important to follow appropriate guidelines and regulations for livestock nutrition and health.
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.
Ephedrine-medicated salt blocks are regulated substances in many countries and not typically available for purchase by the general public. They are usually used in veterinary medicine and are typically available through licensed veterinarians or suppliers. It's important to consult with a veterinarian or local regulatory authority for guidance on obtaining these products.
NaCl. That's it: just plain table salt. And there really is no such thing as a "medicated" salt block.
Yes, because of its *ephedrine* content. Ephedrine is a central nervous system (CNS) stimulant. Stimulants are usually appetite suppressants (anorectics).
Ephedrine has four stereoisomers due to the presence of a chiral center in its structure. Specifically, it has two enantiomers: (R)-ephedrine and (S)-ephedrine, as well as two diastereomers: (R,S)-ephedrine and (S,R)-ephedrine. Therefore, the total number of stereoisomers for ephedrine is four.
