How do drugs work in the brain?
Drugs are chemicals. They work in the brain by tapping into the brain's communication system and interfering with the way nerve cells normally send, receive, and process information. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter. This similarity in structure "fools" receptors and allows the drugs to lock onto and activate the nerve cells. Although these drugs mimic brain chemicals, they don't activate nerve cells in the same way as a natural neurotransmitter, and they lead to abnormal messages being transmitted through the network.
Other drugs, such as amphetamine or cocaine, can cause the nerve cells to release abnormally large amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals. This disruption produces a greatly amplified message, ultimately disrupting communication channels. The difference in effect can be described as the difference between someone whispering into your ear and someone shouting into a microphone.
How do drugs work in the brain to produce pleasure?
Most drugs of abuse directly or indirectly target the brain's reward system by flooding the circuit with dopamine. Dopamine is a neurotransmitter present in regions of the brain that regulate movement, emotion, cognition, motivation, and feelings of pleasure. The overstimulation of this system, which rewards our natural behaviors, produces the euphoric effects sought by people who abuse drugs and teaches them to repeat the behavior.
How does stimulation of the brain's pleasure circuit teach us to keep taking drugs?
Our brains are wired to ensure that we will repeat life-sustaining activities by associating those activities with pleasure or reward. Whenever this reward circuit is activated, the brain notes that something important is happening that needs to be remembered, and teaches us to do it again and again, without thinking about it. Because drugs of abuse stimulate the same circuit, we learn to abuse drugs in the same way.

How come humans don't use their entire brain?
That is a common misconception that has now turned into an urban legend. We do in fact use all of our brain, but not all at once. Different parts of our brain get 'switched on' and used when the need arises for them to be used. For example, if you were looking at something, the parts of your brain dealing with visual images will be active. In this same way we use all of our different parts of the brain, but only when the need arises to do so.

How does the extra dopamine released during drug use affect the brain?
Dopamine is commonly referred to when discussing the rewards system of the brain. This neurotransmitter is responsible for acting as the system for the brain. Thus when extra dopamine is released during drug usage, it causes a positive association with the drug to be formed. In short: More dopamine = more drive to recreate the experience
