Effects On The Brain
Although initial drug use may be voluntary, drugs have been shown to alter brain chemistry, which interferes with an individual's ability to make decisions and can lead to compulsive craving, seeking and use. This then becomes a substance dependency.
All drugs of abuse - nicotine, cocaine, marijuana, and others - effect the brain's "reward" circuit, which is part of the limbic system.
Drugs hijack this "reward" system, causing unusually large amounts of dopamine to flood the system.
This flood of dopamine is what causes the "high" or euphoria associated with drug abuse.
