Special Issue Information
Dear Colleagues,
We understand that addictive behavior seeking is a multi-faceted neurobiological, genetic, epigenetic, personality and spiritual phenomenon, which proves that addictions are not one-dimensional and their occurrence requires currently unknown accompanying factors.
Evidence of a significant degree of inheritance in all types of addictions has led to attempts to identify specific genes. Research is complicated by the fact that addictive behaviors are a complex trait that is heterogeneous in terms of phenotype and genetics. It is believed that the profile of symptoms and the variety of observed behaviors are influenced by numerous gene loci, which differ in the direction of influence and the intensity of the effect. The possibilities of understanding the genetic basis of addiction are further complicated by interactions between different loci (epistasis) and gene–environment interactions. Therefore, although substance abuse and addiction undoubtedly depend on genetic factors, the genetic cross-section of these disorders is more complicated than in the case of traits inherited according to Mendel’s laws.
Advances in genome technology are increasing the ability to unravel many of the complex aspects of substance use disorders, including the role of low-effect genes, and to consider gene–environment interactions. It is hoped that in the future, discoveries made through the use of gene identification techniques combined with the results of functional, developmental, and pharmacological studies of the identified genes will lead to progress in the field of addiction prevention and treatment.
This Special Issue is supervised by Dr. Jolanta Chmielowiec, assisted by our Topical Advisory Panel Member Dr. Kszysztof Chmielowiec (University of Zielona Góra).

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
