woman wonders the difference between fentanyl vs heroin

Opioids are one of the most abused drugs in the United States. They account for thousands of overdose deaths every year. However, opioid is a broad term, and can apply to several different types of drugs. Among the many types of opioids on the streets, heroin and fentanyl are two that lead to many overdoses and addictions. Although there are differences between fentanyl and heroin, they both require the help of a heroin addiction rehab in San Antonio, TX if you become addicted.

Fentanyl Vs. Heroin: How Do They Differ?

The difference between fentanyl and heroin may be subtle because they are both opioids and they both act on the brain in very similar ways. They both bind to opioid receptors in the brain causing a feeling of euphoria and eliminating pain. In addition, these drugs hit the user very rapidly if injected or snorted, making them almost irresistible. To those who go down the pathway of opioid use, withdrawal from these drugs is difficult.


Fentanyl is a synthetic, Schedule II controlled substance. The Drug Enforcement Agency provides the scheduling category and it means the drug is legal for certain medicinal purposes. However, it’s highly addictive and has the potential for abuse.


Heroin is derived from opium and is classified as a Schedule I controlled substance, which means it has no medicinal purposes. Therefore it is illegal to possess.

The Difference

One major difference between fentanyl vs heroin is its schedule category. It must be noted though that fentanyl, although it is a Schedule II controlled substance it is rarely prescribed. When it’s prescribed, it’s for people with terminal cancer who are tolerant to opioids.

Another difference between heroin and fentanyl is that people make fentanyl in superlabs and sell it on the street, which makes it even more dangerous. Often heroin is cut with fentanyl due to its inexpensive cost, thus leading to fatal results.

Another difference between heroin and fentanyl is heroin is semi-synthetic, whereas fentanyl is completely synthetic. This means fentanyl is all man-made.
