Crack cocaine is known for its powerful and immediate effects on the central nervous system, leading to a rapid rush of euphoria shortly after consumption. This euphoric sensation occurs due to the drug's ability to increase dopamine levels in the brain. Dopamine is a neurotransmitter associated with pleasure and reward, and when crack cocaine is used, it causes a significant surge in these levels, producing feelings of intense happiness and well-being. This euphoria can be overwhelmingly strong, which contributes to the drug's high potential for addiction.

In contrast, depression, drowsiness, and focus are not typically associated with the initial use of crack cocaine. Following the euphoric high, users might experience a crash or feelings of anxiety and depression as the effects wear off, but these sensations do not occur shortly after use. Drowsiness is more commonly linked to depressant drugs. While some users may feel more focused on certain tasks while under the influence of stimulants, the primary and most immediate sensation associated with crack cocaine is euphoria.
