Which substance is known for its impairing effects when abused?

Marijuana is known for its impairing effects when abused due to its active compound, tetrahydrocannabinol (THC). THC interacts with the brain's endocannabinoid system, which is responsible for regulating various functions such as mood, memory, and movement. When marijuana is consumed in excessive amounts, it can lead to cognitive impairment, altered perception, and impaired motor skills, which can significantly affect a person's ability to perform tasks that require focus and coordination.

The other options do not produce the same level of impairment. Electrolytes are essential for maintaining hydration and bodily functions but do not have psychoactive properties when taken as recommended. Vitamins are also important for health but do not induce impairing effects when consumed properly. Herbal teas may have mild relaxing or calming effects depending on the ingredients, but they do not typically lead to significant impairment like marijuana does when abused.
