There are differing views on cannabis and phytocannabinoid usage in diverse domains of application. This review explores the advantages and drawbacks of using cannabis and phytocannabinoids, including their effects on human health, in addition to highlighting the need for precise and repeatable analytical methods for quantifying controlled phytocannabinoids in consumer cannabidiol (CBD) products and foods. The composition and characteristics of the phytochemicals found in cannabis, the advantages and disadvantages of controlled and uncontrolled phytocannabinoids, and the need for regulation and standardization in the use of cannabis and products containing phytocannabinoids are all covered in this review of the pertinent literature. Cannabinoids used illegally can have negative consequences, but controlled phytocannabinoids found in consumer CBD products are relatively safe and unlikely to cause any adverse effects. It is necessary to restrict the amount of CBD in foods and consumer products in order to ensure safety. To measure the amount of restricted phytocannabinoids in these products, accurate analytical techniques are also required. In order to increase the use of cannabis among consumers, more research is needed to improve our understanding of the bioavailability and metabolic pathways of these compounds. Furthermore, consumers want clear and uniform federal rules governing the amount of CBD in food products in order to ensure correct dosing. To promote safe and responsible use, cannabis and phytocannabinoids must be carefully considered, regulated, and standardized. It is necessary for consumers to have clear, consistent standards governing the percentage of CBD in their food products. As a result, they would know the exact amount of CBD in their products.
