Epigenetic Mechanisms in Substance Use Disorders

Epigenetics explores how environmental factors influence gene expression without altering the DNA sequence, playing a significant role in substance use disorders. Chronic substance use triggers epigenetic changes that affect brain function, increasing addiction susceptibility and altering stress responses. These modifications can persist across generations, predisposing offspring to similar issues. Understanding epigenetic mechanisms opens avenues for targeted therapies, such as reversing harmful gene expression through pharmacological interventions. Research in this area highlights the potential to break the biological cycle of addiction, emphasizing prevention and early intervention strategies.
