Question

Quizplus · Accepted Answer

Psychoactive drugs move easily from the blood supply into the brain, which is why they produce their effects on behavior. They do not require injection and are often administered through smoking, vaping, or oral ingestion. Microdialysis techniques may be used to study their effects on neurotransmitters in the brain, but this does not indicate the effectiveness of the drug on behavior.
