Cannabis, also known as marijuana, is a plant that has been used for medicinal purposes for thousands of years. In recent years, there has been a growing interest in the therapeutic potential of cannabis, and several countries and states have legalized its use for medical purposes. This has led to significant developments in the regulation of medicinal cannabis, as well as a growing body of research on its pharmacology and therapeutic uses.

The historical use of cannabis for medicinal purposes dates back to ancient civilizations in Asia and the Middle East. In these cultures, cannabis was used to treat a variety of conditions, including pain, inflammation, and anxiety. In more recent history, cannabis was widely used as a medicinal plant in the United States, Canada and Europe, and was commonly prescribed by doctors for a range of conditions.

The pharmacology of cannabis is complex and not fully understood. Cannabis contains more than 100 active compounds, known as cannabinoids, which are thought to be responsible for its therapeutic effects. The most well-known cannabinoid is delta-9-tetrahydrocannabinol (THC), which is the main psychoactive component of cannabis and is responsible for its characteristic “high.”

Cannabis is usually administered orally or inhaled. When taken orally, it is metabolized by the liver, which produces a number of active metabolites. When inhaled, it is rapidly absorbed into the bloodstream through the lungs, which allows for rapid onset of effects. The pharmacokinetics of cannabis can vary depending on the route of administration and the individual characteristics of the patient.

There is a growing body of evidence on the medicinal uses of cannabis. Clinical studies have shown that cannabis can be effective in the treatment of a number of conditions, including chronic pain, nausea and vomiting associated with chemotherapy, and certain forms of epilepsy. It has also been shown to have potential benefits for individuals with mental health conditions, such as anxiety and post-traumatic stress disorder.

The evolving regulations surrounding medicinal cannabis have significant implications for the acute care hospital setting. In many countries, hospitals are now permitted to dispense cannabis to patients who have been prescribed it by a doctor. This has led to the development of new protocols and policies for the storage, dispensing, and administration of cannabis in hospital settings.

In conclusion, the use of cannabis for medicinal purposes has a long and fascinating history. Its pharmacology, pharmacokinetics, and therapeutic potential are the subjects of ongoing research. As regulations surrounding medicinal cannabis continue to evolve, it is important for hospitals to develop appropriate protocols and policies to ensure the safe and effective use of this medication in the acute care setting.
