Write a note on a chemical which interacts with the cannabinoid receptors present in the brain?

Cannabinoids are a group of chemicals that interact with cannabinoid receptors present primarily in the brain.
- Natural cannabinoids are obtained from the inflorescences of the plant $Cannabis \text{ } sativa$.
- The flower tops, leaves, and resin of the cannabis plant are used in various combinations to produce marijuana, hashish, charas, and ganja.
- The main active element is $\Delta-9$ Tetrahydrocannabinol $(THC)$. It causes pupil dilation, increased blood sugar levels, and higher urine formation.
- Generally taken by inhalation and oral ingestion, these are known for their effects on the cardiovascular system.
- Cannabinoids are also misused by some sportspersons to enhance athletic performance.
