August 3 Leave a reply I € m a parent with two older teens and I worry about them using marijuana. I went online to see if there were any home drug testing kits that I can use that will work to detect marijuana in their system. What Type Of Home Drug Testing Product Is Best For Marijuana. I € m wondering which product is best to use when.

I sometimes suspect that my kids may have tried this and I am concerned with them using this drug and also the potential of it being a gateway to other drugs. From what I understand, the best time to test is in the morning before the individual has a silvain to drink any products that can wipe the substance from their system. I found several tests that can be used to test for this drug and most of them work by using a urine sample.

While most sites state that marijuana stays in the system for 7 days, some of the other sites mention that it only stays in there for 3 days.

I also know that there are some detoxifiers that can rid the body of the drug, although I think they have to be taken right before the test.
