Medicinal cannabis, often referred to as medical marijuana, is a category of legal, high-quality medicines that can be prescribed by qualified healthcare professionals to treat various medical conditions and alleviate the side effects of certain treatments. This therapeutic approach involves the use of cannabis-derived products that have been carefully developed and regulated to ensure safety and efficacy.
Medicinal cannabis is derived from the Cannabis sativa or Cannabis indica plants, and it contains a range of chemical compounds known as ‘cannabinoids.’ Researchers have identified between 80 and 100 different cannabinoids in medicinal cannabis, and ongoing scientific investigations aim to understand the specific properties and potential benefits of each of these compounds.
Currently, the two most well-known and studied cannabinoids found in medicinal cannabis are cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC). These cannabinoids play a central role in the therapeutic effects of medicinal cannabis.
CBD is often praised for its non-psychoactive nature, meaning it doesn’t produce the “high” typically associated with cannabis use. Instead, it offers potential benefits such as pain relief, reduction of inflammation, and management of various medical conditions.
