With urine tests, THC can be detected from 3 days to as long as 3 months after use, while saliva tests can detect it for 24 hours after use. Hair drug tests can detect it for up to 90 days. Meanwhile, blood tests can detect THC for up to 36 hours after use. Having said that, drug tests don’t screen for CBD since it isn’t intoxicating unless a lab test is used which is made for detecting CBD specifically. There are dozens of different types of drug tests out there, which all have varying cut-off levels. Legally speaking, hemp CBD products contain 0.3% of THC so it won’t be detected unless you consume extremely high amounts, or unless the drug test was engineered to detect CBD although it is rare for legal and employment reasons.
