Pros and cons of marijuana home drug test kits

There are a lot of parents around the world which remain concerned about their teenagers falling in the trap of marijuana addiction, which is available quite easily through discreet means these days. A majority of them are now turning to marijuana home drug test kits to ensure that any symptom or hint of drug usage is quickly diagnosed, which in turn would help them to keep their children away from such drugs during the tender teen years. However, you need to ensure that you invest some time researching such kits before making a purchase, as many experts now opine that some of the test kits might do more harm than good.
The marijuana home drug test kits are of two types; one which tests urine samples and other which tests hair to detect the presence of the drug in the suspect. Though hair testing kits are more expensive and a bit complicated to use, they have a few advantages. These tests are less invasive, cannot be easily tampered with and the presence of marijuana can be detected long after its consumption. Urine tests, though much easy conduct and less time consuming, have the disadvantage that they prove effective only when the body of the suspect is actually processing drugs.
A typical home based drug test kit would include specimen envelopes and collection materials along with user manual. The test results are quite accurate and take no more than a few minutes to show the results. However, in case the results are positive, make sure that you seek immediate medical attention to tackle the problem head on.
