Dissociative Anesthetics

Dissociative Anesthetics is the category of drugs that includes PCP, its various analogs,

and Dextromethorphan (DXM).

PCP is a synthetic drug that was first developed as an intravenous anesthetic.

Because PCP produces very undesirable side effects, it is no longer legally

manufactured. However, an analog (chemical cousin) Ketamine is still being legally

manufactured and available.

However, it is easy to manufacture:

• The formula for making PCP and PCP analogs have been widely publicized.

• The manufacturing process involves readily available chemicals.

Many Dissociative Anesthetic users smoke the drug, by using it to adulterate tobacco,

marijuana, or various other substances.

Dissociative Anesthetics can also be taken orally or by injection, or inhaled.
