Fatal marijuana poisoning in cattle

Abstract

Marijuana, the narcotic produced from Cannabis sativa, is considered a weak poison for animals. Marijuana toxicosis is not rare in dogs that have access to the drug, although many cases probably go unreported because of legal implications. Clinical signs in dogs resemble those seen in humans: odd behaviour, weakness, tremors, incoordination, salivation and nausea.
