Blood Drug Testing

Has anyone ever taken a home drug test? If so, how accurate was it?

Ok, if you saw my previous question, you know that on Saturday I made the huge mistake of smoking pot. Now true, I haven't had any drugs in my system in years, and I only took 3 hits, but I am still very worried about the drug test I had to take today for employment. I bought and took a home drug test last night, and it came back negative. I was wondering if anyone else has ever taken one of those and if so, was it accurate?

1. In testing to see if someone has recently used pot, there are two important substances to keep in mind: THC and 9-carboxy-THC. 9-carboxy-THC is a product of the body's metabolism of THC and, more importantly, it is detectable for a longer period of time than THC is detectable. This is the reason that drug tests, namely urine tests, look for 9-carboxy-THC. Blood Tests Urine Tests Frequent Users* 4 - 8 hours (THC) 2 or more weeks (9-carboxy) 2 weeks – 1 month† ( 9-carboxy-THC.) Infrequent Users** 3 - 4 hours(THC) 2 - 3 days( 9-carboxy) Up to 10 days (9-carboxy-THC.) The range is based on how high your metabolism is and your weight. So try and come up with a time from the data ive given you. your fine. these tests are actually very accurate
