Is there any lab test to ascertain whether my son is a drug addict. Suppose he had constant drugs on the last three days.

Question

Please note the following in respect to your queries:
The Narco Analysis Test:
In this a person is able to lie by using his imagination. In the Narco Analysis Test, the subject's imagination is neutralised by making him semi-conscious. In this state, it becomes difficult for him to lie and his answers would be restricted to facts he is already aware of.
Experts inject the subject with Sodium Pentothal or Sodium Amytal. The dose is dependent on the person's sex, age, health and physical condition. A wrong dose can result in a person going into a coma, or even death.
The subject is not in a position to speak up on his own but can answer specific but simple questions. The answers are believed to be spontaneous as a semi-conscious person is unable to manipulate the answers.
Also Urine test can be done to identify the same.

Yes there are tests. SRL RANBAXY does them. They are usually done in their central lab in Mumbai. But, please note that there is a separate test for each individual drug and each test costs around 5000. So, you have to know which drug you are testing for and there are some addictive drugs which cannot be tested.
Besides this, some corporate hospitals (high end) do have those tests available.
