genetic factors in addiction

Genetic factors influence addiction by affecting how individuals respond to substances, their cravings, and their likelihood of developing dependence. Variations in certain genes can alter brain chemistry, making some people more sensitive or less sensitive to drugs, which can increase or decrease their risk of addiction. These genetic differences help explain why some individuals develop addictions more easily, even with similar exposures, and why responses to treatment can vary. However, genetics is just one part of the puzzle; environment, life experiences, and mental health also play crucial roles in addiction.
