Here OMICS Group provides scientific journals so you can view the latest information about the Journal of Alcoholism and Drug Dependence .

Drug recognition methods are procedural and consistent evaluation methods for detecting the symptoms of drug addiction. All the areas analyzed are observable physical reactions to specific types of drugs. Three key elements used in the process are

  • Confirming that the individual’s physical reactions vary from normal.
  • Ruling out a cause that is not related to medication.
  • Using analytic techniques to figure out the classification or combination of substances that are likely to cause the impairment.

Drug recognition methods include the recognition of the type of chemical substances ingested, although it is not possible to recognize specific medication within a classification. These methods can figure out whether the youth is currently under the impact of ingredients or has used a particular drug or combination of medication within 72 hours of ingestion. However, it is not possible to figure out the amount of the material consumed.

Use of drug recognition methods provides immediate results with which the youth can be confronted. These methods are non-invasive in discovering illicit medication use, compared with the anthology of body required for urinalysis. The process is regular and consistent, reducing the possibility of bias or mistake by trained staff.

There are 12 steps in drug recognition process:

  • Drug history
  • Breath alcohol test
  • Healthcare psychophysical tests
  • Medical questions and initial observations
  • Evaluation of hypodermic injection sites
  • Evaluation of vital  signs
  • Darkroom examination
  • Evaluation of the eyes
  • Youth’s claims and extra findings by staff
  • Opinions of the evaluator
  • Toxicological examination

Chemical Testing:

Chemical testing is the most invasive and expensive method among the three techniques of determining illegal medication use; however, it is also the most precise method. Several scientific techniques are available for discovering illegal medication use in individuals, such as urinalysis, blood research, hair analysis, and saliva assessments. However, saliva and breathing research for liquor and urinalysis for drugs other than liquor are the techniques currently suggested because they are efficient and relatively affordable when compared to other techniques of chemical testing.

Chemical reaction is shown in the name of the test:

  • Radioimmunoassay (RIA)
  • Latex agglutination immunoassay (LAIA)
  • Enzyme immunoassay (EIA)
