N-methyl-3-piperidyl benzilate is less potent and shorter acting than 3-quinuclidyl benzilate, but like 3-QNB its effects on the central nervous system predominate over peripheral effects. It produces deliriant and hallucinogenic effects similar to those of plants such as datura and may be abused recreationally at low doses, however unpleasant side effects such as dysphoria, nausea and vomiting, dizziness and extreme dry mouth tend to make abuse of these kind of drugs uncommon. Both the N-methyl and N-ethyl analogues of 3-piperidyl benzilate are however Schedule I controlled drugs.

Radiolabelled versions of this drug are used in scientific research to map the distribution of muscarinic acetylcholine receptors in the brain.^[1]
