All psychoactive drugs act on more than one place in the brain. a. True b. False Clear my choice

The answer is **a. True**.While psychoactive drugs may have a primary target or mechanism of action, they invariably affect multiple neurotransmitter systems and brain regions. This interconnectedness and complexity of the brain means that altering one system often has cascading effects on others. This is why many drugs have a range of effects, both desired and undesired (side effects).
