i will be attending (and running xc and track at) a small d3 college next year in a state where pot is legal, and I have a green card. I have a pax vaporizer, and I've consistently improved my xc and track times over the past 4 years (4:45 as a freshie-4:22 as a senior), so it doesn't affect my performance or motivation negatively. would drug tests be getting in the way of my weed-smoking ways? I only really smoke (or vape if you will) once a week, maybe twice, but that said i would dread the random tests. do i have to stop?
