Brief Answer: Wait for few more days until taking lab urine test Detailed Answer: Hi, The most important chemical component of Marijuana is tetrahydrocannabinol (THC), which is detected in the urine test. You are saying to have stopped smoking marijuana prior 4 months from the last use. If habitual use, THC can be shown in the urine test within 2 to 3 months of last use. So, it was supposed after 4 months of last "habitual" use of marijuana, your urine test could be resulted negative. But, you did smoke marijuana 53 days ago (around 1 and half month ago). THC will be detected within 1 to 7 days after single use. However, it will depend on : - the quantity smoked - your kidney and liver function - your body ability to metabolize marijuana (which is genetically determined) while height and weight won't have any effect. As the at home test "keeps showing up", I advise to wait for few more days until taking the urine test. Make sure that you won't have false positive results. Please bare in mind that certain over-the-counter drugs together with foods and beverages can affect the test and give false-positive result. Hope it answered to your query! Let me know if you have more questions! Dr.Albana
