If someone mentions cannabis, what do you picture? For most people, the word brings up images of recreational drug use. But cannabis is actually a family of plants, and not every member of that family gets you high.
Hemp and marijuana are both cannabis plants. They can look almost identical growing in a field. But legally, biologically, and practically, they are completely different things. Understanding this distinction matters whether you are buying skincare products, exploring wellness supplements, or just trying to understand labels at the store.
They Are Both Cannabis, So What Is the Difference?
The term cannabis refers to a genus of flowering plants in the family Cannabaceae. The single most important chemical that separates hemp from marijuana is THC, which stands for Tetrahydrocannabinol. THC is the compound responsible for the psychoactive effect that people experience from marijuana.
- Hemp contains 0.3% THC or less by dry weight.
- Marijuana contains more than 0.3% THC, often ranging from 5% to 30% or higher in modern cultivated strains.

This removed hemp from the Controlled Substances Act, allowing it to be grown, processed, and sold across the country. Hemp is also legal in the EU, Canada, Australia, and the UK with various regulations. India permits industrial hemp cultivation in certain states under licensing.
Frequently Asked Questions
Is hemp a drug?
No. Hemp is a variety of the cannabis plant that contains 0.3% THC or less. THC is the compound that causes psychoactive effects. Hemp does not produce a high and is not classified as a drug under US federal law. Hemp-derived products like hemp seed oil and CBD supplements are legal wellness and food products.
Can smoking hemp get you high?
No. Hemp contains legally less than 0.3% THC, which is not enough to produce any psychoactive effect. Even if someone smoked a large quantity of hemp flower, the THC content is far too low to cause a high.
Is CBD from hemp or marijuana?
CBD is found in both plants, but the CBD products legally sold in stores and online are derived from hemp. This is because hemp naturally has a very low THC content, making it the legal and practical source for CBD in the supplement and wellness industry.
Does hemp have any THC at all?
Yes, but in trace amounts. By legal definition, hemp must contain 0.3% or less THC by dry weight. This tiny amount is not enough to cause any psychoactive effect and is well below the threshold that causes intoxication.
Why did hemp become illegal in the first place?
Hemp was lumped together with marijuana under the Marihuana Tax Act of 1937 and later the Controlled Substances Act of 1970 in the US. This was largely driven by political, economic, and social factors rather than science. The 2018 Farm Bill officially re-separated hemp from marijuana in US federal law.
Is hemp the same as cannabis?
Hemp is a type of cannabis, but not all cannabis is hemp. Cannabis is the broader plant family. Hemp refers specifically to cannabis varieties with 0.3% or less THC. Marijuana refers to cannabis varieties with more than 0.3% THC.
