BACKGROUND: In many health settings, administration of medicinal cannabis poses significant implementation barriers including drug storage and safety for administering staff and surrounding patients. Different modes of administration also provide different yet potentially significant issues. One route that has become of clinical interest owing to the rapid onset of action and patient control of the inhaled amount (via breath timing and depth) is that of vaporisation of cannabinoid products...

In 1937, the United States of America criminalized the use of cannabis and as a result its use decreased rapidly. In recent decades, there is a growing interest in the wide range of medical uses of cannabis and its constituents; however, the laws and regulations are substantially different between countries. Laws differentiate between raw herbal cannabis, cannabis extracts, and cannabinoid-based medicines. Both the European Medicines Agency (EMA) and the United States Food and Drug Administration (FDA) do not approve the use of herbal cannabis or its extracts...

The plant Cannabis sativa contains a number of psychoactive chemical compounds, the cannabinoids, which possess a significant pharmaceutical potential. Recently, the usage of Cannabis for medicinal purposes was legalized in many countries. Thus, the study on the influence of different cannabinoids in combination with other Cannabis-derived compounds with respect to the treatment of various diseases becomes increasingly important. Besides the production of distinct cannabinoids in a heterologous host, like tobacco or yeast, transgenic Cannabis plants would be a suitable alternative to modify and therefore optimize the cannabinoid profile...

Cannabinoids have considerable interest in the pharmaceutical industry. However, the production of medicines from hemp (Cannabis sativa L.) in most countries is restricted by law. Large-scale, field cultivation of hemp is difficult to control. Cannabinoid content in plants is variable and depends on multiple factors. Therefore, alternative methods of production have been investigated. The development of micropropagation techniques is a necessary step for genetic modification. Promising results have been obtained for certain narcotic genotypes...

Hempseed (Cannabis sativa L.) has been used as a health food and folk medicine in China for centuries. In the present study, we sought to define the underlying mechanism by which the extract of Fructus Cannabis (EFC) protects against memory impairment induced by D-galactose in rats. To accelerate aging and induce memory impairment in rats, D-galactose (400 mg/kg) was injected intraperitoneally once daily for 14 weeks. EFC (200 and 400 mg/kg) was simultaneously administered intragastrically once daily in an attempt to slow the aging process...

Although the endocannabinoid system (ECS) is involved in the regulation of several physiological processes, including sleep and the immune response, its role during infections has not been fully studied. It is well known that the use of this drug increases susceptibility to infections because of the impact on the modulation of the immune system. Concerning the medicinal or recreational use of marijuana, its influence on the course of an infection, whether this has been caused by bacteria, viruses, parasites, and to a lesser degree, fungi, has been reported...
