You are 95 pounds and 5'6"...OMG you are skinny which is going to help you clear the THC more quickly. I have seen people pass with StripNC, some fail, it is a crap shoot. You said you only smoke once or twice a month. If your body was completely free of THC before the Thanksgiving smoke then that one time high should clear your body in about 5 days, maybe 3-4 considering how skinny you are. If your test isn't Monday or Tuesday I bet you will be fine. You may want to just do a mild dilution before the test, say drinking about 32-40 ounces of Gatorade the morning of the test and everytime you pee, replace that which is lost with drinking more Gatorade or other sports drink. Dilution is a method where you try to dilute your urine to lower the THC concentration but not to the point where it fails validity testing. Read the dilution sticky.
