Fizz effervescent tablets are an effective product for pre-employment Urine nicotine testing. The directions are different for each type of pre-employment nicotine test being administered. Below you will find directions for pre-employment urine nicotine tests along with a product description. The Quick Fizz is a product that actually holds the nicotine metabolites in your body. Nicotine metabolites are stored in the fat cells of the body. For these nicotine metabolites to be released, the fat cells must be burned and the metabolites are released into the blood stream. The Quick Fizz prevents the body from burning fat cells so the metabolites are never released during a pre-employment nicotine test. The Quick Fizz works on nicotine metabolites and is undetectable. The Quick Fizz is designed for individuals who use nicotine 4 times a week OR LESS. If the individual is over 200 lbs., it is recommended they consume two boxes of Quick Fizz. The effervescent tablets dissolve easily in water and taste great.
