Detailed explanation-1: -Every substance has slightly different effects on the brain, but all addictive drugs, including alcohol, opioids, and cocaine, produce a pleasurable surge of the neurotransmitter dopamine in a region of the brain called the basal ganglia; neurotransmitters are chemicals that transmit messages between nerve cells.
Detailed explanation-2: -Dopamine (DA) is the neurotransmitter that has been classically associated with the reinforcing effects of drugs of abuse and may have a key role in triggering the neurobiological changes associated with addiction.
Detailed explanation-3: -Drugs interfere with the way neurons send, receive, and process signals via neurotransmitters. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter in the body. This allows the drugs to attach onto and activate the neurons.
Detailed explanation-4: -There are four levels of addiction: physical, emotional, mental, and spiritual. We will discuss each level in-depth and provide tips for overcoming addiction. Most people who try drugs or engage in risky behaviors don’t become addicted.
