I'm 17.How do I convince my parents that I'm a hippie and I need to smoke weed ? the trash my stash?

I love smoking weed because mother earth told me that , I need to ascend my body to new levels ya'know...I feel like I need to fly. My parents are all like " Hope! your are not going to destroy your future , you are going to college." I'm like mom forget this future , this is the past future , I'm waiting for the real future , where my alien buds can implant a college experience in my head so I wont need to go to college. :D
