Drug abuse1 is a common phenomenon which virtually confronts all countries in Europe and has also been a major public health issue over the past decades. Monitoring of prescribed and nonprescribed drug use provides valuable information on the diagnosis and management of patients. As such, monitoring can therefore be helpful in confirming drug use and allowing physicians to determine whether the patient is compliant or whether other psychotropic drugs are being used.

Different techniques that can be used to analyze exhaled breath are as follows:
