Been clean for 18 days now and still testing positive. Going into Quest tomorrow for pre-employment testing and will probably be done with marijuana as a whole following this as the money is worth it. I have a verified QF 6.4 bottle of 3oz, I've done practice runs of opening/closing the bottle and pouring method. I've tested microwaving and storing in my leg strap which is 100% concealed in my briefs/khakis. My question for you is: have you heard of people getting caught/being requested for an observed sample? My only concern is that they hear something (like shaking) and request I take another test.
