thanks for the advice, so no one here ever uses the heater that comes with the kit? i'm kind of paranoid now...i really dont want to lose this job! my boss is cool, he said just let him no win i think i will test clean then i can take it again (he probably doesnt no i used last nite) i have 2 kits being shipped to me now. again thanks 4 any help, this is such bullshit! possibly losing a good job over something as safe as sum pot.
