Hello,
You have been
smoking weed for the first time 3 days ago. Since you smoked weed for the first time it can be detected in the urine for 3 days. Hair tests are very sensitive tests
THC can be detected up to 90 days. In the urine it can be detected between 3-30 days after the last use. Detection depends on THC dose, body fat, sex, exercise, hydration,
metabolism.
Stay well hydrated. Take water and fluids throughout the day. Avoid getting dehydrated.
Dehydration increases the concentration of THC. Maintain healthy weight, fat in body slows down cannabis metabolism. Exercising releases THC from the fat cells. Avoid exercising just before the test.
Stay away from any kind of medications, alcohol, smoking, etc. Take healthy home made food and if metabolism is good you will pass the test. Do not get addicted to marijuana. It can affect the health drastically in long run.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
