My partner recently took a drug test (split) and the first spec a was positive at .25 ((cutoff was .15)). he contested the results and currently waiting on specimen b to be tested. how likely are two false positives? can cbd lubricants cause this?

Need more info: What was the specimen tested for? If it was THC, it may not have been false positive. CBD preparations could have THC as a contaminant. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
