Hello,
Thanks for using healthcaremagic.

If you are a regular cannabis smoker it is likely to show THC in your blood and urine samples as it remain the system for two to four weeks.

But in case you are just occasional user than chances are less but still there. For occasional users cannabis can be detected in blood and urine for one to three days.

As you have smoked on Friday chances are very less in compare to chronic smokers.
Thanks and regards
