== Differences between ''Cannabis indica'' and ''Cannabis sativa'' ==
''Cannabis indica'' and ''Cannabis sativa'' are two species of the cannabis plant.<ref name="ref1" /><ref name="ref2" /> French naturalist Jean-Baptiste Lamarck first identified ''C. indica'' in 1785, distinguishing it from Carl Linnaeus's earlier classification of ''C. sativa'' in 1753.<ref name="ref3" /><ref name="ref4" /><ref name="ref5" /> The distinctions were based on observable physical characteristics, known as phenotypes, which arose as the plants adapted to different geographic environments. While these classifications are still widely used to describe the plants' morphology and traditional uses, modern hybridization has led to a wide variety of strains with mixed genetics. Some researchers argue that the sativa/indica distinction is less relevant than a plant's specific chemical profile in determining its effects.

=== Morphological Differences ===
Botanists distinguish between ''C. indica'' and ''C. sativa'' based on their physical traits. *C. indica* plants are typically short, dense, and bushy with woody stalks and broad, dark green leaves. This compact stature is an adaptation to their native windy and harsh mountain climates.

In contrast, *C. sativa* plants are taller and less densely branched, with thinner, lighter green leaves. Their taller, lankier structure and longer flowering times are suited for the warm, humid environments with long growing seasons where they originated.<ref name="ref5" />

=== Geographic Origins ===
The physical differences between the two species are largely a result of their geographic origins. *Cannabis indica* is indigenous to the Hindu Kush mountain range in Central Asia, including regions of Afghanistan, Pakistan, and India.<ref name="ref3" /><ref name="ref4" /> These plants adapted to survive in harsh, dry, and cooler climates.

*Cannabis sativa* originates from warmer, equatorial regions and is native to Southeast Asia, Africa, and Central and South America.<ref name="ref5" /> These plants thrive in humid, tropical climates with long seasons of sunlight.

=== Reported Effects and Chemical Composition ===
The two cannabis species are commonly associated with different effects. *Indica* strains are widely reported to produce calming and sedative effects, often used for relaxation and to aid sleep. *Sativa* strains are generally associated with a more energizing and cerebral experience.

These differing effects are attributed to the unique chemical profiles of the plants, particularly their concentrations of cannabinoids and aromatic compounds called terpenes. While it was once thought that indica strains had higher levels of cannabidiol (CBD) and sativas had higher levels of tetrahydrocannabinol (THC), this is not always the case with modern strains. Research now suggests that the terpene profile may be a more significant indicator of a strain's effects. For example, higher concentrations of the terpene myrcene, known for its earthy aroma, are often found in indica strains and are associated with sedative qualities. Sativa strains may have higher levels of terpenes like limonene, which has a citrus scent and is associated with mood-enhancing effects. Due to extensive crossbreeding, many cannabis strains today are hybrids, containing a mix of both indica and sativa genetics.
