420 (four-twenty): The number once only celebrated by stoners and marijuana enthusiasts is now recognized by a broader, international audience. Learn about the hazy origin of 420, the emergence of cannabis culture, and the history of cannabis in Maine.

The Origin of 420 

420 (or 4/20) began in 1971 when five San Rafael, California high school students would meet each afternoon at 4:20 to smoke up. The term “420” was coined and became the group’s code for meeting up to puff-puff-pass.

In 1990, a group of Grateful Dead fans circulated flyers in Oakland, California inviting cannabis lovers to partake on April 20 at 4:20. One of these flyers landed in the hands of Steve Bloom, a former reporter for High Times Magazine. The magazine printed the 4/20 flyer in 1991, and “420” soon became the designated date/time for all things weed.

Celebrated annually on April 20th, 420 has evolved into an international counter-culture day dedicated to celebrating and consuming cannabis – and fighting for legalization and decriminalization.

Once familiar with 420, you will see signs throughout pop culture (i.e., clocks set to 4:20, price tags showing $420, football game scores at 4-20 in movies, etc.)

The History of Cannabis in Maine 

The history of cannabis in Maine is one of gradual acceptance, legal milestones, and significant societal change. Like many states, Maine saw cannabis primarily as an agricultural product in the 19th and early 20th centuries – using hemp for its strong fibers in making ropes, sails, and other products. However, by the mid-20th century, cannabis was largely illegal, and its use was heavily stigmatized.

Fast forward to the late 20th century, the state took its first major step towards legal cannabis use by legalizing medical marijuana. In 1999, Maine one of the earliest states to legalize medical marijuana, reflecting a growing trend towards acceptance of cannabis for therapeutic purposes. The Maine Medical Marijuana for Specific Illnesses Act allowed patients with certain conditions to use cannabis under medical supervision.

Facing Challenges for Recreational Cannabis in Maine

In 2016, Maine voters approved the Marijuana Legalization Act, making Maine the ninth state in the U.S. to legalize the recreational use of cannabis. The law allowed adults aged 21 and over to possess up to 2.5 ounces of cannabis and to cultivate a limited number of plants for personal use.

However, the rollout of recreational cannabis in Maine was not without challenges. With many regulatory hurdles and delays, it wasn’t until October 2020 that a recreational cannabis dispensary had its first sale
