Using a more sensitive cutoff of 20 ng/mL (less common but still used by some labs), the most likely maximum times are 7 days and 21 days, respectively. In extraordinary circumstances of extended marijuana use, detection times of more than 30 days are possible in some individuals at the 20 ng/mL cutoff.sing a more sensitive cutoff of 20 ng/mL (less common but still used by some labs), the most likely maximum times are 7 days and 21 days, respectively.

Full Answer. 1  Prepare hot and cold tubs Fill a pan with enough water to submerse an entire chicken and heat it to around 160 degrees Fahrenheit. Have another pan full of slightly chilled water nearby. 2  Scald the chicken Dip the chicken carcass in the hot water for 5 to 10 seconds. Keep hold of the bird's feet and swirl it around slightly while it is in the water to make sure that the heat penetrates between all the feathers. Pull the chicken out quickly to keep the skin from cracking.
Sprinkle salt into the water. You can sprinkle anywhere from 1 tsp (5 ml) to 1 Tbsp (15 ml) salt into the water. A smaller amount is better for boneless chicken breasts and chicken tenders, but a larger amount may be better for whole chickens.
