Carena has taken a drug that produces striking perceptual changes. wherever she looks right now, she sees beautiful butterflies, objects glowing and changing shapes, and colors are rich and vibrant. it is most likely that carena has taken?

It is most likely she has taken LSD.

Explanation:

LSD is a hallucinogen, which means it creates hallucinations (seeing, or hearing things that are not there, for example). This drug does not allow one to separate fantasy from reality and it affects the individual's perception.

LSD takes the place of serotonin (a neurotransmitter) on the brain, which is in charge of regulating one's mood. It also makes the brain mix the sensory pathways, thus creating a temporary synesthesia, such as hearing colors.

In this case, Carena has had perceptual changes and she is hallucinating butterflies, seeing objects glow and change shapes and even having a sharp look. It can be concluded that she has taken LSD.
