2 days doesn't give you much time, but do LOTS of running, exercising, and sweating ... you can't 'dilute' THC in your system, it stores itself in fat cells, it has to be 'worked' out ... you'll probably be OK, my son made it into the Army, after a positive, the recruiter told him to come back in a couple weeks (they're looking for 'warm bodies', not athletes) ... Basic Training will get it outta your system
