420, as the name implies, is celebrated annually on April 20. It is an international celebration during which people come together to consume cannabis and advocate for its legalization. Cannabis is widely acknowledged to be a simple plant that has complex effects on the human body. The plant contains chemicals known as cannabinoids. Those that campaign for cannabis to be more widely accepted and available point towards research that suggests some of these cannabinoids, such as CBD, have valuable therapeutic effects on people experiencing chronic pain or undergoing chemotherapy.

History of 420

You can be forgiven for thinking 420 has more origin stories than the Marvel Universe. One popular rumor is that “420” is the code police officers use to signal to each other that marijuana smoking is taking place. Another theory tries to attribute the date to a Bob Dylan song.The most concrete evidence of the holiday’s origins, however, can be traced back to San Rafael high school in Marin County, California. A group of students, known as the “Waldos,” because they used to hang out by a wall, came into possession of a map that they thought would take them to a field full of marijuana. Map in hand, they met at 4:20 pm and eagerly tried to locate the crop. While they left empty-handed that day, 420 became their thing and the term began to spread among their friends.Fast forward half a century, the holiday has taken on a more purpose-driven tone, providing a platform for scientists, medical professionals, politicians, and cannabis consumers to discuss the medicinal benefits of the plant. While the Controlled Substances Act’s categorization of marijuana means it cannot be sold under federal law, the use of marijuana for medicinal purposes is legal in 36 states (at the time of writing), with an increasing number also legalizing recreational use too.This year on 420, we are joining with many others to promote access to safe, legal, and natural cannabis products as many Americans believe that cannabis products can contribute towards a better quality of life.

6 Facts About Cannabis

  1. Cannabis contains more than 500 compounds

    These include terpenoids, flavonoids, and cannabinoids. Cannabinoids are compounds that are unique to cannabis. The most well-known cannabinoids are delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) — these are the main two that are used in medicine and THC also produces the “high” that cannabis is associated with.

  2. Common consumption methods

    The three most common methods of consumption are ingesting, inhaling, and topical treatment (applying products to your skin). Depending on where you live, edibles, vapes, and oils are among the many cannabis products now legally available from reputable dispensaries.

  3. Conclusive evidence

    The National Academies of Sciences, Engineering, and Medicine state that there is conclusive evidence that cannabinoids can help manage chronic pain in adults, nausea that arises because of chemotherapy, and some symptoms of multiple sclerosis.

  4. Two million patients

    Data from May 2018 shows that there are over 2 million legal medical marijuana patients in the U.S. The same data suggests that the number would be 3.5 million if medical marijuana was legal in all 50 states.

  5. Humans have receptors

    Chemicals in marijuana connect with specific parts of the brain, which are known as receptors. Scientists have identified cells in our brains and immune systems that have cannabinoid receptors.

  6. A legal battle

    According to the Last Prisoner Project, 40,000 people are currently in prison in the U.S. for cannabis-related offenses that are now legal. It is the mission of many to redress the past through legal intervention and legislative advocacy.
