Special Issue Information
Dear Colleagues,
Addiction to drugs is one of the most serious health problems worldwide. Although a great amount of research has been performed in recent decades, many aspects remain unknown, and there are large numbers of people suffering from this issue. Importantly, the progression of drug addiction involves alterations in normal brain circuitry that result in long-lasting drug-induced neuroplastic changes. Critical neurotransmitters (i.e., gamma-aminobutyric acid, glutamate, dopamine, opioid peptides, serotonin, acetylcholine, endocannabinoids, corticotrophin releasing factor) and neurocircuits (i.e., ventral tegmental area, nucleus accumbens, amygdala, cerebellum, prefrontal cortex) underlie the pathological changes at each of these stages. Thus the mechanisms underlying how one becomes addicted to drugs need to be elucidated further and through more diverse approaches, including the molecular pathway. Additionally, many studies on pharmacological or nonpharmacological therapeutics have been shown to be effective during several phases of drug addiction, such as sensitization, self-administration, withdrawal syndrome, craving, and relapse. However, the limitations of their adverse effects and the fact that these scientific mechanisms are not fully understood make us hesitant to use them. In addition, the interaction mechanism through which negative factors such as stress or emotional problems induce or accelerate addiction during each phase cannot be excluded from addiction research. Finally, the scientific approach must examine evidence related not only to functional disorder or unbalance but also structural plasticity to obtain a complete view of the problem. In this Special Issue, we would like to invite any molecular research providing scientific evidence that helps us to better understand drug addiction and the treatments for it.

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.
