Cannabis has been used for different purposes since the past, and although the interest in cannabis is increasing day by day, the cannabis plant has been avoided for a while. Underlying the consumer's negative opinion of hemp is the psychoactive substance content of the plant. Contrary to popular belief, cannabis cultivated for industrial purposes is a cannabis variety with reduced psychoactive substance content and legal limits to support consumption. Although trans-Δ9-tetrahydrocannabinol (THC) in cannabis, which is responsible for the psychoactive effect, is an objectionable component that should be considered in industrial cannabis production, cannabidiol (CBD), which has the same molecular weight, has analgesic for chronic and non-chronic pain, antiepileptic, antibacterial, anti-inflammatory, anticarcinogenic, antidiabetic, antidepressant properties. THC component is not found in cannabis seeds, which are used as food for protein source purposes. In this study, the chemical properties of trans-Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) compounds, which have the same molecular properties, were compiled by examining their effects on health, applicable legal limits, and research on compounds.
