Morphine pharmaceuticals are subject to annual manufacturing quotas; in 2017 these quotas were 35.0 tonnes of production for sale, and 27.3 tonnes of production as an intermediate, or chemical precursor, for conversion into other drugs. Morphine produced for use in extremely dilute formulations is excluded from the manufacturing quota. Internationally (UN), morphine is a Schedule I drug under the Single Convention on Narcotic Drugs. Non-medical use
The euphoria, comprehensive alleviation of distress and therefore all aspects of suffering, promotion of sociability and empathy, "body high", and anxiolysis provided by narcotic drugs including the opioids can cause the use of high doses in the absence of pain for a protracted period, which can impart a morbid craving for the drug in the user. As the prototype of the entire opioid class of drugs, morphine has properties that may lead to its misuse.
