• Cultivating the Quality of Patience, Part II

    This is the final installment in a two-column series focusing on embracing the quality of patience in enhancing both the success and overall quality of recovery from alcoholism and/or drug addiction.


  • The Need for Cross-Cultural Counseling in Addiction Treatment

    The new push for addiction counselors these days is to be client centered. This means a big push on compassion, collaboration, and especially meeting clients where they are, but what does that really mean? To meet clients where they are, should we have to understand their cultures? And if so, how do we do so?


Researchers Develop Fingerprint Test for Drug Use

News Briefs

Researchers from Surrey University in England worked with the Netherlands Forensic Institute and Intelligent Fingerprinting to design a fingerprint test capable of detecting cocaine and other drug use (Burch, 2017; Johnston, 2017). 


The test is called “paper spray mass spectrometry” and works by analyzing two different molecules in fingerprints that are “excreted as a person’s body metabolizes drugs” (Burch, 2017). These molecules can still be seen in fingerprint tests after subjects have washed their hands. There is a specific kind of paper used to take the fingerprints and detect the molecules, and it has a 99 percent accuracy rate (Johnston, 2017). 


“This is a real breakthrough in our work to bring a real time, noninvasive drug-testing method to the market that will provide a definitive result in a matter of minutes—we are already working on a thirty-second method,” stated researcher Dr. Melanie Bailey from Surrey University (Burch, 2017). Dr. Bailey added that the test is “hygienic and can’t be faked—by the nature of the test, the identity of the subject, and their drug use, is all captured within the sample itself” (Johnston, 2017). 


While the test can detect other drugs such as heroin, researchers are unclear as to if it “could be used to reliably detect marijuana use, or whether it can indicate a level of impairment of just the presence of drugs in a person’s system” (Burch, 2017).
