Cannabis is one of the most talked-about plants in the world, yet the words we use to describe it can vary wildly. Some people call it weed, others prefer marijuana or pot, while in professional and medical spaces it’s almost always referred to as cannabis. Each of these terms carries its own history, cultural weight, and context.
The language surrounding cannabis has evolved for more than a century, shaped by politics, science, and popular culture. As legalization spreads and more people enter the cannabis conversation, the importance of terminology becomes even more relevant. Do all these words mean the same thing, or do they represent different sides of the same plant? Let’s break it down.
A Brief History of Cannabis Terminology
Marijuana
The word marijuana (or marihuana) originates from Spanish and was first recorded in the late 1800s and early 1900s. In the United States, the term gained heavy use during campaigns that politicized and stigmatized the plant. Today, while still widely understood, “marijuana” is increasingly being replaced by “cannabis” in legal and medical contexts.
Cannabis
Cannabis is the scientific name of the plant species — Cannabis sativa, Cannabis indica, and Cannabis ruderalis. It’s the most accurate and neutral term, and it’s the one most commonly used by lawmakers, researchers, and the global medical community.
Weed
The slang term weed surfaced in the United States around 1929. It quickly became one of the most popular and casual words for cannabis, especially in pop culture, music, and everyday conversation.
Pot
The word pot entered the conversation in the late 1930s, reportedly derived from the Spanish phrase potación de guaya, referring to a cannabis-infused wine. It became another go-to slang term, especially throughout the mid-20th century.
Are Weed, Cannabis, Marijuana, and Pot the Same Thing?
So, do weed, cannabis, marijuana, and pot all mean the same thing? In short – yes. Each of these terms is used to describe the same thing. While each of these terms came at their respective times, each is interchangeably used. It’s hard to say if one is more popular over another, but weed and cannabis seem to be the most widely used in current day.

Cannabis vs. Hemp
It’s important to note that not all cannabis is psychoactive.
- Cannabis → The umbrella term for the plant species as a whole.
- Hemp → A type of cannabis bred to contain very low levels of THC (0.3% or less in the U.S.) but higher levels of CBD. Hemp is commonly used for wellness products, clothing, rope, food, and industrial uses.
- High-THC Cannabis → Often referred to as weed, pot, or marijuana, this is the form most commonly associated with psychoactive effects.
So while weed, marijuana, and pot typically mean THC-rich cannabis, hemp is non-psychoactive and primarily associated with CBD. CBD-focused cannabis plants are typically referred to as hemp or CBD, while these other terms are typically used to only describe high-THC cannabis.

For brands, media, and consumers, the choice of word can shape the message — whether casual, medical, or cultural.
