If you ask for coc , its out of metabolic system pretty fast 2-3 days BUT allot depends on quality and quantity, your body type and metabolism, etc.. Also if you smoke it stay for longer then if you snort it so add 2-3 days extra. Also detection time for hair drug test is 90 days. If its drug test involved check at your local pharmacy for home drug test kit many places have single panel COC drug test kit. (urine and some times saliva)
