The instructions say to store the kit between 40 and 85 farenheit. Could placing the kit outside on concrete on a hot 90+ farenheit day, break the kit without it being obvious?

I know you guys are smart as fuck. Help me figure out how to tamper with my mother's marijuana drug test. I am of age. Am literally 21, but cannot afford testing positive because she pays for my college and I need my college education. She is religious. I use CBD and THC to alleviate my severe spinal pain she is aware of yet insists on me refusing allievance from weed and using other means instead (That I take advantage of but don't work as well as weed and exercise) Exercise is fine yeah but weed helps me calm down and alleviate the pain in the fucking mean time I can't have a hot bath 24/7.
