Which type of drug is commonly associated with feelings of happiness and energy?

Stimulants are commonly associated with feelings of happiness and increased energy due to their effects on the central nervous system. When consumed, stimulants elevate mood and promote alertness by increasing the levels of neurotransmitters like dopamine and norepinephrine in the brain. This amplification of neurotransmitter activity can lead to enhanced feelings of well-being, heightened energy levels, and increased motivation.

In contrast, depressants tend to have the opposite effect, often leading to relaxation and sedation rather than elevation in mood or energy. Dissociatives may cause a disconnect from reality, which doesn't typically correlate with happiness and energy. Antidepressants are medications designed to treat depression; while they can help to improve mood over time, they don't provide the immediate energetic effects associated with stimulants.
