Step 1: Identify the Question

The question is asking for a specific type of drug that accelerates the activity of the central nervous system.

Step 2: Analyze the Options

1. Gateway Drugs: These are substances that may lead users to try more dangerous drugs, but they do not specifically increase central nervous system activity.
2. Depressants: These drugs slow down brain function and can lead to sedation. They are the opposite of what is being asked.
3. Stimulants: These drugs increase alertness, attention, and energy by raising the levels of key neurotransmitters in the brain.
4. Hallucinogens: These are substances that cause changes in perception, mood, and cognitive processes but do not primarily speed up the central nervous system.

Step 3: Determine the Correct Answer

Since the question specifically asks for drugs that speed up the central nervous system, the correct answer is:

Stimulants

Final Answer

Stimulants are drugs that speed up a person's central nervous system.
