It doesn't work: and you shouldn't be trying. Niacin is potentially toxic in high doses, and doses greater than 1000 mg per day are not recommended. It can cause severe headache and problems related to vasodilatation. Neither working out nor drinking water will increase your clearance of THC, and overly dilute urine will cause you to "fail" a urine drug test. Stop using cannabis and it will take care of itself.

Niacin when used even for lowering lipids is now not recommended and not effective. Stopping use of THC is best option.
