The dependency of individuals upon drugs and other stimulants has no doubt increased within society over time. Previously, researchers have had little luck in finding evidence of the origin of such substance addiction. However, recently it has been established that certain genes associated with alcohol addiction are in fact also closely related to dependence of other stimulants such as cocaine, cannabis, heroin, opioids and nicotine. “Addiction researchers have found that several genes are linked with multiple addictions,” states Ming Li, a professor of psychiatry and neurobehavioral sciences. According to these researchers, once they are able to locate the correct genetic variants, they will be able to generate more effective treatments, than those of current use, for individuals suffering from substance addictions. So far, scientists have found specific genomic locations on 11 chromosomes where dependencies of these substances are grouped together. Through the comparison of peaks on these certain chromosomal locations, it has been confirmed that genetic susceptibility to different substances overlaps. With continual genetic advances about the occurrence and vulnerability of substance addictions, knowledge such as this will certainly benefit society in the combat to overcome severe addiction problems, in turn, potentially saving many lives.
