Below is an overview of the activity The Role of Microorganisms in the Ecosystem (American. Society of Microbiology, Mark Gallo and Shannon Ventresca) to incorporate information learned. from Dr. Kerkhofâs presentation and subsequent discussion.
Blood tests are more sophisticated than we think. While THC can be detectable in the blood of non-regular marijuana smokers up to 27 hours after consuming, regular smokers can be caught within up to nearly 90 days. Furthermore, it is not for sure: in some cases, the detection period turns out to be even longer.
On a Urine Drug Test, THC will appear as a positive within 2-5 hours of use. How long it will still show on a urine drug test is estimated based on frequency of use, but does not take into account the weight and body fat of the marijuana user:1  One Time User may show positive for 1-6 days. 2  Moderate User may show positive for 7-13 days.n a Hair Drug Test, THC will show up about 7 days after use and most hair drug tests will test for a 90 day period. However, THC does not always bind to the hair follicle which makes it not always considered an accurate testing method for marijuana use.
