What is a common outcome for a client who injected heroin one hour ago?

The common outcome for a client who injected heroin one hour ago is euphoria. Heroin is an opioid that works by binding to opioid receptors in the brain, leading to feelings of intense pleasure and a state of relaxation. This sense of euphoria is often one of the most sought-after effects by users and is characterized by a deep sense of well-being and reduction in pain perception.

While dilated pupils may occur due to different factors, they are not typically associated with heroin use; in fact, opioid use commonly results in miosis, or constricted pupils. Other effects such as nystagmus and tachypnea may not directly relate to heroin’s primary pharmacological effects at this stage. The primary and most notable outcome after heroin injection is the euphoric feeling experienced by the user.
