>>20912119This guy has probably got the best advice, especially if your state or probation department uses a lab. A lab will see any dilution or masking drinks. The only hope with that is powdered or someone elses urine that is clean.
Google the state you're in and see if probation uses labs. If it's only a stick test then mask or drink a ton of water and my former advice above. If they use a lab then Whizzinator or rig something with a camel pack and some hand warmers using powdered pee etc.
If that's not possible just be honest. They usually wont violate on the first offense especially if you're honest.
Tell them you smoked THC-A which is legal across the United States.
