forget he flush kit. thc is fat souluble not like chemicals that can be flushed. water water water , first quit totaly not even a hit. then drink water like a camle. dont over do it water can be toxc if you drink too much. do you know what type oesting will be done, ie: urine, hair,or the new common way is by swab, swab in the mouth only detects thc for 48 hrs. 9 days to cleen up is not actualy unreasonable and remember somtimes they arent even looking for pot. i just dont want you to waste your moneyon a flush kit ,your other option is to substitute your urine for clean pee. you can buy it over the net , sythetic or freez dried. if you have to pass or els you should go that way just remember unfortunatly nothing you take internaly can fool a test for pot, you need a clean sample, one i know works is urineluck.try to google it. god luck. God bless.
