blood test - for the love of god i need help

ok, most of what i have seen here is all urine and hair testing help

for my life insurance company, im taking a REAL drug test, fucking straight up blood

ive been a pretty habitual smoker, at least 3 or 4 bowls a day for about 5 months, with some breaks, a 2 1/2 week break at one point, a few one or two day breaks, and today is july 14th, my test is in just under 2 weeks

how the fuck do i clean my BLOOD out?

i read that excercising can increase metabolsim and get the fucking THC metabolites out, but is there anything else?

methinks im totally fucked
