Detox drinks are too hit or miss. I know people who swear by them and those who have failed. It is too hit or miss. They (the drink) either are performing a dilution, which you can learn about here and do for under $10, or they have a massive amount of fiber, which you can buy 10 times as much fiber for under $10 by picking up some Metamucil. Some people who do pass are also using the detox in conjunction with dilution.

It is pre employment, that means unobserved unless you tip them off or refuse to empty your pockets or take off outwear like jacket or coat. Keep smoking and sub, it is easier. Get a clean friend's urine and freeze it or keep searching online. Even if Quick Fix is illegal in NY, you will find someone online who still ships to NY. Then practice getting the temp right after you secure it to your body. Practice, practice.
