do i have anything to worry about? drug test.

[Burnt Toast]

I didn't drink water with it though

So what youre saying is that you did not follow the directions of use...

Heaven Sent Omni Cleansing Drink Fruit Punch Directions
1) Shake well, drink entire contents.
2) Drink plenty of water
3) Urinate frequently to expel pollutants

so is that still considered dilution?

It most certainly is. Regardless if its the magic potion, water, gatorade, cranberry juice, chocolate milk, etc; anytime you consume fluids, an effort is being attempted to dilute the THCA concentration that is present in the bladder. "Attempted" is the operative word here. Thats because dilution techniques (regardless of configuration) can backfire if the THCA concentration is too high. For most longtime heavy users, it would be virtually impossible to dilute that concentration enough without overdiluting and sending up the red flags at the lab.

And I had read about water & b12 but wasn't sure if it worked or not

The proper vitamin to use for urine "color" is B2 (Riboflavin), not B12.
