Narcotics are a class of drugs that cause insensibility or stupor by depressing the central nervous system. The term "narcotic" often refers to opium, its derivatives (like morphine, codeine, and heroin), and synthetic substitutes (such as meperidine and methadone). However, the term "opioid" is now more commonly used and preferred due to less ambiguity.
Types of Substances Included in the Term "Narcotic"
The composition of narcotics can vary, encompassing both natural and synthetic substances. Here's a breakdown:
-
Natural Narcotics: These originate from the opium poppy plant. Key examples include:
- Opium: The raw, unprocessed form containing numerous alkaloids.
- Morphine: A potent analgesic derived from opium.
- Codeine: A weaker analgesic also derived from opium, often used in cough suppressants.
- Heroin: A semi-synthetic derivative of morphine, significantly more potent and addictive.
-
Synthetic Narcotics: These are manufactured in laboratories and mimic the effects of natural opiates. Examples include:
- Meperidine (Demerol): A synthetic opioid analgesic.
- Methadone: A synthetic opioid used in medication-assisted treatment for opioid addiction.
The Shift Towards "Opioid"
While "narcotic" remains in use, the term "opioid" is increasingly favored. This is because "opioid" specifically refers to substances that act on opioid receptors in the brain, providing a clearer and more scientific classification. Both opiates (natural substances from the opium poppy) and opioids (both natural and synthetic) fall under this broader category.
Many sources, including the DEA, suggest using the term "opioid" instead of "narcotic" to avoid confusion. This shift reflects an ongoing evolution in the understanding and terminology surrounding these substances. Therefore, although "narcotic" historically encompassed these substances, "opioid" is the currently preferred and more precise term.
