Drug Testing

Drug Rehab for Teens

 

Drug testing is the most effective way to determine whether an individual has alcohol or substances in their body and if so, what substances were used.

There are several common forms of drug testing- urine, hair, oral fluid/saliva, sweat and blood.  As the chart shows below, hair follicle drug tests can show traces of alcohol and substances much longer than that of urine, blood and saliva.

Drug Rehab for Teens values the importance of helping keep a recovering addict or alcoholic stay honest in his or her sobriety.
