How long do the drugs stay in your system that probation officers test for?

Designer drugs drugs less than 24 hrs, like club drugs.

Cocaine, meth, heroin 24 hours

Marijuana 24 hrs to 30 days, THC is stored in the fat cells so the fatter you are the longer it stay in. Pregnant women could smoke a joint and it could stay in the system 6 months.

Alcohol is less than 24 hours but new test can detect alcohol use up to 7 days out. The test for enzimes rather than alcohol.

SPICE about seven days.
