This may come as a shock to you, but human life hasn't evolved much in the last century. We are just as susceptible to opiates today as we were a hundred years ago.

Genetic factors account for about half of the likelihood that an individual will develop addiction. Environmental factors interact with the persons 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. - American Society of Addiction Medicine
