Psychiatrists and other behavioral health professionals need to better understand the relationship between cannabis and mental disorders so that they can respond to increasing medical and recreational marijuana use among their patients. More than half of states now allow for medical use, and 8 states and the District of Columbia have legalized adult personal or recreational use.

Knowledge about herbal cannabis, the endocannabinoid system, and cannabinoid pharmacology is rapidly expanding. However, compared with the literature on non-medical cannabis use, the scientific literature on therapeutic use of cannabis is underdeveloped, as noted in a recent systematic review of medical cannabis and mental health.1 Although herbal cannabis has a long history of medicinal use, its federal prohibition under the Controlled Substances Act of 1970 with Drug Enforcement Administration Schedule I status has focused the federally supported cannabis research agenda for half a century on the potential harms rather than on the historically acknowledged therapeutic benefits of this complex plant.

Medicinal potential of cannabis

For the sake of this discussion, herbal cannabis refers to plant material derived from the flowering tops of Cannabis indica, sativa, or ruderalis biotypes. Indica, sativa, and indica-sativa hybrid strains are commonly available on the medicinal cannabis market.

Researchers from The University of Queensland have discovered the active compound from an edible mushroom that boosts nerve growth and enhances memory.

Professor Frederic Meunier from the Queensland Brain Institute said the team had identified new active compounds from the mushroom, Hericium erinaceus.

Imagine going for an MRI scan of your knee. This scan measures the density of water molecules present in your knee, at a resolution of about one cubic millimeter – which is great for determining whether, for example, a meniscus in the knee is torn. But what if you need to investigate the structural data of a single molecule that’s five cubic nanometers, or about ten trillion times smaller than the best resolution current MRI scanners are capable of producing? That’s the goal for Dr. Amit Finkler of the Weizmann Institute of Science’s Chemical and Biological Physics Department.

In a recent study (Physical Review Applied, “Mapping Single Electron Spins with Magnetic Tomography”), Finkler, PhD student Dan Yudilevich and their collaborators from the University of Stuttgart, Germany, have managed to take a giant step in that direction, demonstrating a novel method for imaging individual electrons. The method, now in its initial stages, might one day be applicable to imaging various kinds of molecules, which could revolutionize the development of pharmaceuticals and the characterization of quantum materials.

Not only were women in ancient Egypt responsible for the nurturance and admonition of children, but they could also work at a trade, own and operate a business, inherit property, and come out well in divorce proceedings. Some women of the working class even became prosperous. They trained in medicine as well as in other highly skilled endeavors. There were female religious leaders in the priesthood, but in this instance, they were not equal to the men. In ancient Egypt, women could buy jewelry and fine linens. At times, they ruled as revered queens or pharaohs.

The role of women in ancient Egypt diminished during the late dynastic period but reappeared within the Ptolemaic dynasty. Both Ptolemy I and II put the portraits of their wives on the coins. Cleopatra VII became a very powerful figure internationally. However, after her death, the role of women receded markedly and remained virtually subservient until the 20th century.

Patients who received the treatment had less severe brain symptoms and better daily functioning 90 days after the stroke, as compared with those who received clot treatment and a placebo medication.

Butylphthalide is approved and available for use in China, where the study was done. But the medication hasn’t been approved for use by the FDA.

“This is the first trial to show the benefit of using a medication that protects the brain from damage caused by a lack of oxygen to brain tissue. The medication was given to patients with acute ischemic stroke who were also receiving treatment to restore blood flow to the brain,” says co-author Baixue Jia, MD, a doctor of interventional neuroradiology at the Beijing Tiantan Hospital and the China National Clinical Research Center for Neurological Diseases in Beijing.
