Unlikely to pass: In infrequent cocaine users like you described yourself ,it may show in the urine for3to5to days. But those who abuse it regularly it may remain positive for 2 to3 weeks.Cocaine breaks down rather quickly but the urine test is done for the metabolite of cocaine Benzoylecgonone and that can show in urine for 3 to 5 days.One can dilute the urine by drinking lots of water but there is no guarantee.

Likely: Cocaine has a short half life and you are likely to pass the test. Please note that alcohol and cocaine is a dangerous combination and can kill due to heart arrhythmia. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
