Will Delta-8 THC Make You Fail a Drug Test?

Delta-8 THC is a federally legal alternative to delta-9 THC, capable of producing a milder euphoric high. However, it can interfere with delta-9 tests in both presumptive and definitive urine drug tests, according to Quest Diagnostics medical scientific liaison Jack Kain of PharmD. If you consume delta-8 products that exceed the 0.3% delta-9 THC limit, you will fail a drug test. Heavy Delta 8 users should be prepared to test positive for 30 to 60 days, and sometimes even longer.

If you don't pass a drug test due to Delta 8 THC, the best thing to do is talk to your employer or school. If you want to try Delta 8 but want to make sure you don't get dirty on a drug test, it's best to refrain from taking any product containing this cannabinoid for at least 30 days.
