Cannabis refers to the plant Cannabis sativa. The cannabis plant originally comes from Asia. It is now cultivated all over the world, including in Canada. While cannabis in general is said to have originated in Central Asia, the indica plant, more specifically, comes from regions in the Middle East.
Places like Afghanistan, Pakistan or Tibet: this makes sense considering that some of the OG varieties pay homage to their birthplace and are given names like Afghan Kush. The exact lineages and the reasons why this particular strain thrived in these regions are not entirely clear, although, like most plants, it's probably due to climate and location. Marijuana comes from a plant called hemp. Its scientific name is Cannabis sativa.
The main active ingredient in marijuana is THC (short for delta-9-tetrahydrocannabinol). This ingredient is found in the leaves and flowering parts of the marijuana plant. Hashish is a substance that is extracted from the upper part of female marijuana plants. It contains the highest amount of THC.
Researchers say psychoactive cannabis spread from East Asia to India about 3,000 years ago. Over the past thousand years, the drug reached Latin America and Africa, although it didn't reach North America until much more recently, in the early 20th century. European settlers introduced hemp varieties to North America in the 17th century, which were replaced by Chinese varieties in the 1850s. The current climate and economic scenario promotes the use of sustainable resources to reduce our dependence on petrochemicals and minimize the impact on the environment.
Plants are precious natural resources, because they can supply both phytochemicals and lignocellulosic biomass. In this review, we focused on hemp (Cannabis sativa L. We deal with aspects related to the use of hemp biomass and, more extensively, those related to its wide variety of phytochemicals. They include cannabinoids, terpenes and phenolic compounds (Flores-Sanchez and Verpoorte, 200) and will be described in more detail in the following sections.
The prenylation of olivetolate by a hemp transferase produces cannabigerolic acid, the precursor to tetrahydrocannabinol. Despite advanced analytical techniques, much of the cannabis consumed for recreational purposes is not precisely classified. Marijuana is called by many other names, such as cannabis, weed, hashish, joint, Mary Jane, marijuana, joint, marijuana, marijuana. The scientific debate over taxonomy has had little effect on the terminology widely used by growers and users of drug-type cannabis.
Workflow showing achievements (in green) and possible future approaches (in light blue) to produce cannabinoids in cannabis crops, as well as in other host plants. Temporal evolution of cannabinoid accumulation and chemotype development during the growth of Cannabis sativa L. In addition to being present in the central nervous system and throughout the brain, CB1 receptors are also found in immune cells and in gastrointestinal, reproductive, adrenal, cardiac, pulmonary and bladder tissues, where cannabinoids can also exert their activities. In 1545, cannabis spread to the Western Hemisphere, where the Spanish imported it to Chile for use as fiber.
Ultimately, researchers find strong genetic differences between hemp and medical cannabis in their study. The authors discovered that after 28 days of culture in the dark, a peak in the accumulation of cannabinoids could be observed in culture media supplemented with different concentrations of indole-3-acetic acid (IAA). In the report, author Barney Warf describes how cannabis use originated thousands of years ago in Asia, and has since reached many regions of the world, eventually spreading to the Americas and the United States. Regarding the revival of interest in cannabis phytochemicals today, the results of these studies will be available soon.
In fact, the THC content of recreational cannabis has increased dramatically over the past 30 years (from 3% in the 1980s to almost 20% today, as reported in the Table), with a very low level of other cannabinoids, such as CBD. . .
