Which drug is commonly snorted and produces a sense of euphoria and increased energy?

Cocaine

Cocaine is the drug that is commonly snorted and produces a sense of euphoria and increased energy. It is a powerful stimulant that affects the central nervous system. When cocaine is snorted, it is rapidly absorbed into the bloodstream through the nasal tissues. It interferes with the reuptake of neurotransmitters like dopamine, leading to an accumulation of dopamine in the brain. This excess dopamine results in the pleasurable effects of euphoria, increased energy, and heightened alertness that are associated with cocaine use.

Morphine is an opioid analgesic used for pain relief, while barbiturates and benzodiazepines are depressant drugs that have sedative and calming effects. They act on the central nervous system to induce relaxation and sleepiness. However, these drugs are not typically snorted for their effects.
