Will belladona show positive uds

Yes, belladonna can show up on a urine drug screen (UDS), particularly because it contains atropine and scopolamine, which may be detected as anticholinergic substances. However, standard drug tests typically do not specifically test for belladonna or its components. If a test is specifically designed to look for these compounds, then it could yield a positive result. Always consult with a healthcare professional regarding any medications or substances.
