Which factor does NOT contribute to the development of substance use disorder?

The choice of consuming healthy foods stands out as the correct answer because it does not have a direct correlation with the development of substance use disorder. In fact, a healthy diet can often promote overall well-being and resilience against substance use. Nutrition can influence mood and health, possibly making individuals less vulnerable to turn to substances for coping or satisfaction.

On the other hand, cultural norms, access to the substance, and the age when first using a substance are all significant factors that can influence the likelihood of developing a substance use disorder. Cultural norms can dictate the acceptability and prevalence of substance use, while easier access to substances often increases consumption and potential abuse. Additionally, the age at which an individual first uses a substance can be critical; earlier initiation into substance use is frequently linked to a higher risk of developing dependency issues later in life. Therefore, these factors are instrumental in understanding the complexities of substance use disorders.
