The common biomolecular mechanisms underlying addiction – CREB and ΔFosB – were reviewed by Eric J. Nestler in a 2013 review. [3] Genetics and mental disorders may precipitate the severity of a drug addiction. It is estimated that 50% of healthy individuals developing an addiction can trace the cause to genetic factors. [4]

They instead emphasize the individual ...
