Opioid addiction is a complex disease that requires a long-term treatment in most cases.
Opioids are substances that exert their effects via the so-called opioid receptors in the body.
A distinction is made between:
- endogenous opioids: These are the body’s own opioids; they are produced by the body itself and fulfil a physiological function.
- exogenous opioids: These are opioids supplied from outside (due to therapeutic necessity or abuse in the context of addiction).
Exogenous opioids include, for example, methadone, fentanyl, hydromorphone, diacetylmorphine (heroin, the most addictive opioid), buprenorphine and morphine.
