More or less. While cannabis in general is said to have originated from Central Asia, the Indica plant more specifically came from regions in the Middle East. Places like Afghanistan, Pakistan or Tibet - this makes sense considering some of the OG strains pay homage to their birthplace and are given names like Afghan Kush. The exact lineages and reasons as to why this particlar strain thrived in these regions aren't entirely clear, although like most plants, it's probably a result of climate and location.
On the other hand, Sativa strains were typically found in Southeast Asia in places like Thailand, Cambodia and Laos, and eventually made their way to Central America where they're now found naturally in Mexico and Brazil.
Cannabis also occurs naturally in cold places too! However, it's not the smokeable kush you're used to. Instead, cannabis exists in places like Russia, Hungary and Ukraine as cannabis ruderalis, which is more similar to wild plants and weeds. While this kind of cannabis plant can't get you high, it's believed to be descended from hemp plants. The more you know.
