any drink that has both niacin and ginsing will work.
Also forgot to mention that drinking shit load of water would work as well. The way this works is. Everytime you take a piss it will pass some thc thru it pending on how much water you drink and how many times and how much piss comes out when you go to the bathroom. This takes about 1 gal of water a day for 2 weeks on avg. To keep track your thc lvls go to walgreens or any other store that cares drug tests. This will help you determine if you are doing fine or need to use a method even more.
Pretty much THC stays in your fat solubles. So each person is different on how long it takes it to get out of the system pending on how much fat they have.
