Navigating the world of CBD products comes with its own set of questions and considerations, and one that often arises is, “Is CBD legal in my area?” and “What are the age requirements?”
The CBD industry has only recently been made legal at the federal level through the 2018 Farm Bill, and individual states have made their own laws regarding CBD since. The legal landscape surrounding CBD can be a bit complex, with variations from one place to another.
In this guide, we'll break down the age requirements for purchasing CBD, helping you understand the rules and regulations in place. Whether you're a curious consumer or a parent looking for information, we've covered the age-related aspects of buying CBD products. Let’s dive into the details.
Is CBD Legal?
The legal status of CBD can be complex. According to the 2018 Farm Bill, hemp-derived CBD products containing less than 0.3% THC are federally legal, whereas marijuana-derived CBD remains illegal under most circumstances.
Although this legislation legalized CBD at the federal level, individual states retain the authority to determine its legality within their borders, establishing their own regulatory frameworks. For a more comprehensive analysis, refer to our guide “Is CBD Oil Legal in the USA?”
Following state-level determinations of CBD legality, the issue of age restrictions for purchasing CBD arose, with individual states establishing their own policies.
While this discussion will focus on state-level age restrictions, it is crucial to recognize that local (county or city) ordinances may differ from state regulations. Therefore, verifying the specific laws applicable in your area is always wise.
Federal Age Limit (What the Law Says Now)
When Congress passed the 2018 Farm Bill, there was no mention of a minimum age to purchase or use CBD. This means that, technically, at the federal government level, anyone — including minors — can buy hemp-derived CBD products.
That said, because states control the enforcement of CBD laws, many places have added their own age restrictions for purchasing CBD products.
States With No Age Restrictions (for Hemp-Derived CBD)
In these states, hemp-derived CBD products are legal, and lawmakers have not created any official minimum age requirement for purchasing CBD. That means retailers can sell CBD to adults and minors, although stores may choose to set their own rules as a precaution.
Even though the state does not enforce a legal age, many retailers still prefer to sell CBD only to adults to avoid legal confusion. Because of this, real-world access may vary from store to store.
No state-level age restriction applies in:
Alabama • Arizona • Arkansas • Iowa • Maryland • Missouri • Nebraska • New Jersey • Texas • Virginia • West Virginia
Consumers in these states can generally purchase hemp CBD freely, as long as the product meets federal standards—specifically that THC content stays below 0.3% and the CBD is derived from the hemp plant, not marijuana.
States Where You Must Be 18 or Older
Is CBD legal for 18 year olds? These states require consumers to be at least 18 years old to purchase CBD products. This rule usually applies to hemp-derived CBD, although some states have additional guidelines based on THC levels, licensing requirements, or medical use restrictions.
In many of these states, CBD with any detectable THC may fall under medical cannabis plant laws, meaning an 18+ requirement still applies, and in some cases, a medical cannabis card may be necessary.
These states currently set the minimum age at 18:
California • Colorado • Delaware • Florida • Hawaii • Idaho • Kansas • Kentucky • Louisiana • Massachusetts • Michigan • Minnesota • Mississippi • Montana • Nevada • New Hampshire • New Mexico • New York • North Carolina • North Dakota • Ohio • Oklahoma • Oregon • South Carolina • South Dakota • Vermont • Washington • Wisconsin • Wyoming
Key notes to understand:
- Idaho and Kansas require that CBD contain no detectable THC, which can restrict the types of CBD available.
- Kentucky and South Carolina have tighter rules around CBD used for medical purposes, which may require a doctor’s recommendation.
- Some states enforce stricter rules for inhalable or smokable CBD, even if other forms are allowed at 18.
Even within these states, individual retailers may still set a 21+ policy for certain CBD product types.
States Where the Age Requirement Is 21+ (or More Restrictive)
Do you have to be 21 to buy CBD? A smaller group of states has chosen to set the CBD purchasing age at 21 or older. These states often have tighter cannabis regulations in general, and they may treat CBD products similarly to tobacco or adult-use cannabis products—especially if the product contains measurable THC.
In some of these states, marijuana-derived CBD is only available through licensed dispensaries, and the customer must be at least 21 or have a medical cannabis card.
States with 21+ rules include:
Alaska • Illinois • Maine • Rhode Island • Tennessee • Utah
What this means for buyers:
- Retailers must verify age before selling CBD.
- CBD products with THC—such as full-spectrum formulas—may have additional restrictions.
- In some states, the only CBD legally available outside a dispensary must be hemp-derived and below the federal THC limit of 0.3%.
Customers in these states should always double-check whether the product they want is legal to buy without a medical card, since many “21+ states” also tie rules to the type of CBD (full-spectrum, broad-spectrum, isolate).
Which CBD Products Are Safe Based on Age Laws
At the federal level, hemp-derived CBD remains legal without age restriction. However, states may enforce rules separately. Also, some states treat inhalable CBD (like vapes) or THC-containing products differently, often restricting them to adults 21+.
Because of these differences, it’s smart to:
- Check local state laws before purchasing or using CBD.
- Confirm the THC content on any product label.
- Prefer hemp-derived CBD products with low THC to avoid legal complications.
Can a Minor Use CBD?
Legally under federal law — yes. But practically, most recommendations are cautious. Because there is limited data on CBD’s long-term effects for children and teens, many experts recommend that minors only use CBD if a doctor advises it.
If you are a parent considering CBD for a minor, talk to a physician first to weigh risks and potential benefits.
CBD and Drug Testing
One frequent concern among CBD users — especially working adults or athletes — is drug testing. Even though CBD itself does not show up on standard tests, THC content can trigger a positive result.
If you’re subject to testing, it’s safer to choose THC-free products like broad-spectrum CBD or CBD isolate. Always check lab reports to make sure THC levels are effectively zero or below detectable limits.
Sum It Up
So, how old do you have to be to buy CBD? The answer depends heavily on your state laws. Federally, hemp-derived CBD is legal, and no age is specified. But many states have implemented their own age limits or rules.
If you’re buying CBD, check local laws carefully. Look for hemp plant-derived CBD, verify THC content, and choose products from trusted, reputable sources. Whether you’re 18, 21, or older — or even a parent researching for a minor — staying informed is your best bet.
