The fast-acting barbiturate known for its significant abuse liability is Nembutal. This medication, also known as pentobarbital, is often used for its sedative effects and is classified as a central nervous system depressant. Due to its quick onset of action, Nembutal can produce powerful feelings of euphoria, which contributes to its potential for abuse.

In the context of addiction and substance use, Nembutal’s rapid effects make it appealing for those seeking immediate relief from anxiety or insomnia, leading to an increased risk of misuse. Furthermore, the risk of developing tolerance and dependence is heightened with Nembutal due to these euphoric properties. This makes it a substance of concern among addiction counselors, as it can lead to serious health issues including overdose.

While other options such as Phenobarbital and Ambien (zolpidem) also have sedative effects, they do not carry the same level of abuse potential as Nembutal. Barbitura, which may not be a recognized standard term in pharmacology, does not refer to a specific substance and is less relevant in this context. Thus, Nembutal stands out as the notable barbiturate with significant abuse liability.
