Internet Addiction: The Making of a New Addiction
Karin H Bergmark*, Einar Stensson, Anders Bergmark
The body of Internet addiction research articles has grown rapidly during the last years. Critics claim that the bulk of this research is more confirmatory than scrutinizing, in spite of weak evidence for the label of addiction. A study on excessive Internet use in Sweden has been cited repeatedly in Internet addiction studies. The present study takes a closer look at these citations and combines the presentation with a systematic review of methods and theoretical approaches in Internet addiction studies, published between January 2000 and July 2013.
Phenotypic Traits and Genetic Markers Associated with Smoking
Carlos A. Isaza M, Julieta Henao B, Leonardo Beltrán*, Sandra Valencia C, Alejandra Quiceno G
Smoking is a complex addiction, with heterogeneous phenotypic traits and marked genetic influence. In this study, we compared the variant rs1137115 of the CYP2A6 gene, which encodes the enzyme that metabolizes nicotine, and variant rs16969968 of the CHRNA5 gene, which encodes the receptor to which nicotine binds, between smokers and non-smokers. We assessed any associations between these molecular markers and phenotypes of smokers.
