Food substances are commonly used to prepare drugs. For example, the drug MDMA is often prepared from the chemical methamphetamine, which is also made from a food substance-methamphetamine hydrochloride. Other drugs that are prepared with food substances include cocaine and heroin.
Some people argue that using food substances to prepare drugs is dangerous because it can lead to contamination of the drugs with harmful chemicals. Others say that this method of preparation makes it easier for people to get access to drugs, especially in countries where drug laws are weak or non-existent.
