Can you detect castor oil in a urine sample?

Yes, castor oil can be detected in a urine sample, primarily through the identification of its metabolites. Castor oil contains ricinoleic acid, which can be metabolized and excreted in urine. However, specific testing methods would be required to confirm its presence, as castor oil is not typically included in standard drug screenings. The detection may also depend on the amount ingested and the timing of the sample collection.
