I am happy to introduce this Special Topic Issue on Addictions and Technology. The issue begins with a Guest Editorial by Dr. Karen Allen. Dr. Allen's editorial provides a look at how technology transfer occurs and the ways in which technology is making an impact in the field of substance use and addictions.

This issue includes five great articles: (a) by Kazemi and colleagues who conducted a systematic review of the literature regarding the efficacy of app-based technological interventions delivered by mobile devices for reducing substance use; (b) by Balmumcu and Atan who report on research out of Turkey regarding the development of a transtheoretical model, based on "WhatsApp" texting technology for use in smoking cessation; (c) by Heitkamp and colleagues whose article discusses examples of how addiction and mental health technology transfer centers improve delivery of addiction prevention, treatment, and recovery services; (d) by Moore, Goyle, and Rodriguez who present results from a study that examined the impact of using "telehealth" technology with medication-assisted treatment in opioid use disorder treatment; and, finally, (e) by Xiaoping and colleagues who report on their research out of China that investigates telephone follow-ups combined with the smartphone app "WeChat" utilized in smoking cessation.

During the COVID pandemic, the healthcare field has seen a large increase in the use of telehealth and other technologies. As technology continues to evolve, it is up to us to stay abreast of what is new, both in the United States and the world, and to explore how these technologies may be used in the field of addiction science. I am hopeful that this Special Topic Issue on Addiction and Technology will provide an overview of some of the advances in technology transfer and utilization. Ultimately, the final goal is to utilize available technologies to promote optimal patient outcomes.
