how long until cocaine is out of your blood for first time users
Cocaine generally stays in your system for about 2-4 days. In fact, this is the detection window for urine for most casual users. However, chronic or heavy cocaine users may have a much longer detection window.s with other drugs, cocaine concentrations in hair are visible for at least 90 days after dosing. However, cocaine does not leave its marks at the root of the hair, but to specific areas. That means that it is there until the hair falls out or is cut off.
