1. What Is Cannabis (Ganja)?
Cannabis is a plant belonging to the Cannabaceae family. It contains more than 100 biologically active compounds known as cannabinoids.
The most important cannabinoids are:
- THC (Tetrahydrocannabinol) – psychoactive (causes “high”)
- CBD (Cannabidiol) – non-psychoactive (medical benefits)
Cannabis is commonly consumed in different forms:
- Smoking (joints, pipes)
- Vaporizing
- Edibles (food, drinks)
- Oils, tinctures, capsules
- Topical creams
2. Types of Cannabis
2.1 Cannabis Sativa
Known for energizing and uplifting effects. Often associated with creativity and focus.
2.2 Cannabis Indica
Known for relaxing and sedative effects. Often used for pain and sleep disorders.
2.3 Hybrid Cannabis
A combination of both sativa and indica traits.
3. How Cannabis Works Inside the Human Body
The human body has a natural regulatory system called the Endocannabinoid System (ECS).
The ECS plays a vital role in maintaining balance (homeostasis) by regulating:
- Pain sensation
- Mood and emotions
- Sleep cycles
- Appetite and digestion
- Immune response
- Memory and learning
Cannabinoids from cannabis interact with ECS receptors:
- CB1 receptors – primarily in the brain and nervous system
- CB2 receptors – primarily in the immune system and organs
