Drug addiction is also an example of attentional bias in that certain memories or objects can prompt intense cravings to one's drug of choice. It is easier for individuals who experience this to relapse and begin their drug use again, because the urges given off by that initial stimuli can prove to be too strong to curve. There are some ways that individuals could overcome attentional bias, and a solution is stimuli-related therapy. This type of therapy would give those struggling with addiction and relapse an opportunity to overcome the initial fear associated with a particular object. A study conducted by a group of researchers in the Netherlands found that by giving participants an opportunity to attend therapy sessions during their treatment for drug addiction, more participants remained drug free compared to those who relapsed. Therefore, the conclusion can be drawn that with exposure therapy, the number of patients who will leave a treatment facility and relapse decreases. The Stoop Test also showed in this study that between the control group and the treatment group the only major component of the test was time; researchers made the claim that those who received treatment reacted a lot faster to certain drug related stimuli versus those in the control group who did not. This means that when experiencing attentional bias, treated addicts seemed to brush off the memories a little easier compared to those who had not received proper treatment. In other words, certain steps need to be taken in treatment facilities across the country to ensure that drug addiction no longer rises, or continues to ruin people's lives. Also, a therapy of this kind should be closely monitored and mandatory to ensure the smallest number of relapses occur after treatment.
