Hemp and marijuana are often confused, but they are not the same. While they come from the same plant species, they are used for different purposes, regulated differently, and contain very different levels of THC.


Understanding the difference is especially important in Iowa, where medical marijuana is legal, but recreational use is not. At the same time, federal laws around hemp and marijuana are continuing to evolve, making it more important than ever to stay informed.


Hemp and Marijuana Come From the Same Plant

Hemp and marijuana both come from the cannabis plant. This is why they can look, smell, and grow similarly.


The main difference between them is how much THC they contain. THC is the compound that causes the “high.”

  • Hemp contains very low levels of THC (0.3% or less), and some products may contain no THC at all, depending on how they are processed

  • Marijuana contains higher levels of THC, with the possibility of having a greater impact on one’s mental and physical state


This one difference affects everything from how the products are used to how they are regulated.


What Is Hemp?

Hemp is a part of the cannabis plant that contains very low levels of THC, the compound responsible for the “high.”


By federal definition, hemp must contain 0.3% THC or less by dry weight. Because of this low THC content, hemp does not produce intoxicating effects.


Common Uses of Hemp

Hemp is widely used in everyday products, including:

  • Skincare and wellness products

  • Clothing and textiles

  • Paper and building materials

  • Food items like hemp seeds and oils


Most hemp-derived products are focused on wellness and do not cause a high.


What Is Marijuana?

Marijuana is another form of the cannabis plant, but it contains higher levels of THC.


In general, marijuana is defined as cannabis with more than 0.3% THC. This higher THC content is what leads to the psychoactive effects many people associate with marijuana.


Common Uses of Marijuana

Marijuana is commonly used for:

  • Medical purposes, such as managing pain, anxiety, and other conditions

  • Recreational use in states where it is legal


In Iowa, marijuana is legal for medical use, and patients can participate in the state program with approval from a licensed healthcare provider.


Key Differences Between Hemp and Marijuana

THC Content

The most important difference is the amount of THC:

  • Hemp: 0.3% THC or less

  • Marijuana: More than 0.3% THC


This difference determines whether a product can cause a high.


Effects on the Body

  • Hemp: Does not produce a high

  • Marijuana: Can cause psychoactive effects like euphoria, relaxation, or altered perception


These effects depend on THC levels and individual tolerance.


Uses and Accessibility

  • Hemp: Found in retail stores, online shops, and wellness products

  • Marijuana: Available only through licensed dispensaries. Medical marijuana products are typically more strictly regulated and tested


Regulation and Safety

Hemp products can vary in quality and oversight depending on where they are purchased. When hemp products are bought at places like gas stations, smoke shops, or grocery stores, they are often not strictly regulated, which means quality, labeling accuracy, and safety standards can vary widely. This can make it difficult to know exactly what you are getting, including the true amount of THC or other ingredients in the product.


Medical marijuana products, on the other hand, are:


This added level of regulation can provide more confidence in product safety.


Why the Difference Matters

The distinction between hemp and marijuana affects more than just terminology. It impacts:

  • What products are legal

  • How products are regulated

  • What kind of effects you can expect


In recent years, some hemp-derived products with higher THC-like effects have entered the market. Federal and state regulators are working to clarify and tighten these rules, especially as laws continue to evolve.


Legal Status

Hemp and marijuana are treated very differently under the law, but federal rules around marijuana are starting to shift.

  • Hemp: Federally legal and widely available, though still regulated

  • Marijuana: Currently classified as a Schedule I substance under federal law, meaning it is illegal at the federal level


Federal officials are reviewing a proposal to reschedule marijuana to Schedule III. If finalized, this change would recognize accepted medical use and could ease certain restrictions, especially around research and taxes. Even with this potential shift, marijuana would not become fully federally legal.


At the state level, laws still apply. In Iowa, marijuana is permitted through the state’s medical program, and patients must be approved to legally access it.


Hemp vs. Marijuana in Iowa

In Iowa, the differences are especially important:

  • Hemp-derived products like CBD are widely available

  • Marijuana is legal for medical use

  • Patients can access medical marijuana through a simple approval process


Getting started is easier than many people think. Patients just need to meet with a licensed healthcare provider, who will determine if medical marijuana is a good option for their needs. Once approved, the next step is completing a quick state registration. With the right guidance, this process can be fast and stress-free, allowing patients to legally purchase marijuana from licensed dispensaries.


Understanding these rules can help you stay compliant while confidently choosing the option that works best for you.


Final Thoughts

Hemp and marijuana may come from the same plant, but they are used in very different ways.

  • Hemp is low in THC, non-intoxicating, and federally legal

  • Marijuana contains higher THC levels and is more strictly regulated
