Strains that grow in these dry regions must adapt to the constant change of temperature that occurs during the day and night.
These subtropical regions are also a common climate in which various strains of marijuana can grow naturally. These strains typically need to live and grow in a moderate environment and would struggle if placed in a region that is extremely hot, cold, dry, or wet.
Popular Strains in Tropical Regions
A significant portion of marijuana strands thrive in this type of climate which is why tropical regions around the world are often the headquarters of cannabis producers looking to create large quantities of product.
Many experts believe that marijuana originated in South and Central Asia and was able to spread across virtually every area of the globe over a period of hundreds of years.
Cannabis plants are believed to have evolved on the steppes of Central Asia, specifically in the regions that are now Mongolia and southern Siberia, according to Warf. The history of cannabis use goes back as far as 12,000 years, which places the plant among humanity’s oldest cultivated crops, according to information in the book “Marihuana: The First Twelve Thousand Years” (Springer, 1980).
Burned cannabis seeds have also been found in kurgan burial mounds in Siberia dating back to 3,000 B.C., and some of the tombs of noble people buried in Xinjiang region of China and Siberia around 2500 B.C. have included large quantities of mummified psychoactive marijuana.
In 1930, Harry Aslinger became the first commissioner of the Federal Bureau of Narcotics (FBN) and undertook multiple efforts to make marijuana illegal in all states. In 1937, the Marijuana Tax Act put cannabis under the regulation of the Drug Enforcement Agency, criminalizing possession of the plant throughout the country.
“Many early prejudices against marijuana were thinly veiled racist fears of its smokers, often promulgated by reactionary newspapers,” Warf wrote in his report. “Mexicans were frequently blamed for smoking marijuana, property crimes, seducing children and engaging in murderous sprees.”
“For the most part, it was widely used for medicine and spiritual purposes,” during pre-modern times, said Warf, a professor of geography at the University of Kansas in Lawrence. For example, the Vikings and medieval Germans used cannabis for relieving pain during childbirth and for toothaches, he said.
