According to the National Institute on Drug Abuse (NIDA), opioids flood the brain with dopamine, creating an intense feeling of pleasure. This intense high is what is known as **opioid-induced euphoria**, a powerful effect that drives the cycle of addiction for many users.

In a study of over 1.14 million non-surgical hospital admissions, 51% of patients received opioid medications, with morphine being administered in 20% of cases [1.8.1]. The fundamental question for understanding its effects is: **is morphine an agonist, antagonist, or reuptake inhibitor?** Morphine is unequivocally classified as a full opioid agonist [1.2.1].

First isolated from opium in 1803, morphine is a powerful analgesic often used to manage severe pain. It is essential to understand **what class of opioid agonist is morphine?** to comprehend its potent effects, the mechanism behind its action, and the associated risks.

According to the FDA, poison control center cases involving tianeptine exposure surged from just 11 total cases between 2000 and 2013 to 151 in 2020 alone [1.7.2, 1.5.4]. This highlights the urgency in understanding its properties, but how strong is tianeptine compared to morphine?

In 2022, an estimated 9.3 million U.S. adults needed treatment for opioid use disorder (OUD), but only 25.1% received medications for it [1.5.4]. Methadone, a key medication in OUD treatment, works because of what it mimics in the body: other opioids and natural pain-relieving chemicals [1.2.2, 1.2.4].
