Does THC seltzer show up in a urine test?
Yes. Urine tests screen for the presence of THC metabolites, specifically THC-COOH, which is created as the body processes THC. Consumption method doesn’t matter—whether you choose THC seltzers or other products—nor does the source of THC (hemp versus marijuana). Exact detection windows vary depending on your metabolism, body composition, dosage, and how regularly you consume THC. That’s why detection windows can range from a few days to a few weeks from one person to another.
