your implied assertion that HUMANS in America are not susceptible to the same BIOCHEMICAL addictions as are HUMANS in Asia.

I made no such implication - that's your functional illiteracy talking.

Here's what the American Society of Addiction Medicine says:

“Genetic factors account for about half of the likelihood that an individual will develop addiction. Environmental factors interact with the person’s biology and affect the extent to which genetic factors exert their influence. Resiliencies the individual acquires (through parenting or later life experiences) can affect the extent to which genetic predispositions lead to the behavioral and other manifestations of addiction. Culture also plays a role in how addiction becomes actualized in persons with biological vulnerabilities to the development of addiction.”

I made no such implication - that's your functional illiteracy talking.

There can be no other explanation for your assertions.

The problem with biochemical addiction is fundamental human biochemistry. If the chemicals didn't tamper with human biochemistry, they could not be addictive.

I'm not interested in reading your psychobabble arguing that there is any other component. Outliers are irrelevant to massive majorities.
