Alcohol and other drugs produce a positive feeling at first, but when the effect wears off, it leaves a person with opposite feelings of depression and irritability. The body's normal production of chemicals in the brain, which ordinarily produce feelings of pleasure, are suppressed, sending the brain into a state of depression. It physically demands more of the drug to go back to "normal'' and feel good again. This pleasure/tension cycle leads to physical loss of control over the use of alcohol and other drugs - and results in addiction.
Neurophysiology of addiction involves changes in the brain's reward system, specifically impacting neurotransmitters like dopamine, GABA, and glutamate. Chronic exposure to addictive substances can alter the brain's circuitry, leading to cravings, loss of control, and compulsive drug-seeking behavior. This process involves changes in areas such as the nucleus accumbens, prefrontal cortex, and amygdala, which play roles in motivation, decision-making, and emotional processing.

Yes, because drug addiction changes the brain in fundamental ways. Drug Addiction is defined by the DSM4 manual (any condition, if it does exist, is in this manual) as a "brain disorder". Therefore, drug addiction is an illness and it is very real and treatable.
Smoking
Probably the major barrier consists of misunderstandings about the nature of what is commonly called addiction.
Journal of Neurophysiology was created in 1938.
