Hemp is legal in Pennsylvania as long as it contains no more than 0.3% THC on a dry weight basis, and hemp-derived products meeting that threshold can be bought, sold, and possessed without a state license. Growing or processing hemp is a different matter and requires a permit from the Pennsylvania Department of Agriculture (PDA). A federal law taking effect on November 12, 2026 will narrow what counts as legal hemp, which matters most for intoxicating products like delta-8 THC.
What Counts as Legal Hemp
Federal and Pennsylvania law both define hemp as the cannabis plant (Cannabis sativa L.) and its parts, seeds, extracts, and derivatives with a delta-9 THC concentration at or below 0.3% on a dry weight basis.1Office of the Law Revision Counsel. 7 USC 1639o – Definitions Pennsylvania’s General Permit mirrors that definition.2Pennsylvania General Assembly. General Permit Standards and Requirements for Hemp
Cross the 0.3% line and the plant stops being hemp. It becomes marijuana, which Pennsylvania’s Controlled Substance, Drug, Device and Cosmetic Act classifies as a Schedule I controlled substance.3Pennsylvania General Assembly. Pennsylvania Act 64 – Controlled Substance, Drug, Device and Cosmetic Act Possessing or selling material above the threshold outside Pennsylvania’s medical marijuana program can trigger criminal penalties.
Buying and Possessing Hemp Products
You do not need a state permit to wholesale, retail, broker, or possess compliant hemp products in Pennsylvania.4Commonwealth of Pennsylvania. Hemp Program FAQs Hemp-derived CBD products with no more than 0.3% delta-9 THC are legal to buy and keep, and the state has not set a possession limit.
Pennsylvania has no statewide minimum age for purchasing hemp-derived CBD products. Some retailers set their own cutoffs at 18 or 21, but that is store policy rather than state law. Before buying, look for a Certificate of Analysis (COA) from a third-party lab. A COA confirms the THC content and screens for contaminants, and its absence is a warning sign.
Some categories carry extra requirements. Selling hemp as food, animal feed, or seed may bring in other Pennsylvania regulators beyond the PDA hemp program, and sellers making health claims face FDA and FTC scrutiny.
Delta-8 THC and Other Intoxicating Hemp Products
Hemp-derived delta-8 THC, delta-10 THC, and similar intoxicating cannabinoids have sat in a legal gray area in Pennsylvania. These products spread through gas stations, vape shops, and convenience stores because they technically met the 2018 Farm Bill’s definition of hemp while producing psychoactive effects comparable to marijuana.
That window is closing. State legislation has been introduced to ban intoxicating hemp-derived THC products, and some Pennsylvania law enforcement agencies have already started enforcement actions against retailers. Federal law is moving in the same direction, as described below. Anyone currently selling delta-8 products in Pennsylvania should treat the current environment as temporary.
What Changes on November 12, 2026
The 2018 Farm Bill removed hemp from the federal Controlled Substances Act but defined it using only delta-9 THC.5Food and Drug Administration. Hemp Production and the 2018 Farm Bill That left room for products loaded with other cannabinoids like delta-8, delta-10, and THCA to qualify as hemp as long as their delta-9 THC stayed under 0.3%.
P.L. 119-37, signed in November 2025, rewrites the federal definition of hemp in three ways that take effect November 12, 2026:6Congressional Research Service. Change to Federal Definition of Hemp and Implications for Federal Policy
- The 0.3% threshold now applies to total THC, not just delta-9. THCA and other THC variants count toward the limit.
- Any finished hemp-derived cannabinoid product containing more than 0.4 milligrams of total THC per container falls outside the definition of hemp.
- Cannabinoids that cannot be produced naturally by the cannabis plant, or that were synthesized outside the plant, no longer qualify as hemp.
Products that fail to meet the new definition will be treated as marijuana under the Controlled Substances Act.7Congressional Research Service. Changes to the Statutory Definition of Hemp and Issues for Congress For growers, total THC testing is harder to pass because THCA, which converts to THC when heated, is abundant in flower. For product makers and retailers, the 0.4-milligram container cap removes most intoxicating hemp products from the legal market.
CBD in Food, Drinks, and Supplements
Hemp itself is legal, but the FDA takes the position that CBD cannot be added to conventional food or sold as a dietary supplement under current federal law. The agency’s reasoning is that CBD is the active ingredient in an FDA-approved drug (Epidiolex), and the Federal Food, Drug, and Cosmetic Act bars it from being introduced into food or supplements on that basis.8Food and Drug Administration. FDA Regulation of Cannabis and Cannabis-Derived Products, Including Cannabidiol (CBD)
CBD-infused foods and drinks are nonetheless sold widely in Pennsylvania. The FDA has not pursued mass enforcement, but it has sent warning letters to companies making drug-like claims, and the FTC has acted against misleading advertising. Topical cosmetics face a lower bar than ingestibles but still cannot carry therapeutic claims without FDA approval. If you manufacture or sell CBD edibles, beverages, or supplements, you are operating in a space where federal enforcement could intensify.
Growing or Processing Hemp in Pennsylvania
You cannot grow hemp in Pennsylvania without a PDA permit, and personal-use cultivation is not allowed under any circumstances.2Pennsylvania General Assembly. General Permit Standards and Requirements for Hemp Permits run on a calendar-year basis and do not auto-renew. The fee is $150 for a new permit and $50 for a renewal.9United States Department of Agriculture. Pennsylvania General Permit Standards and Requirements for Hemp Every applicant and key participant must submit fingerprints for a state and FBI background check, and anyone with a state or federal controlled-substance felony conviction in the last 10 years is disqualified.
Pennsylvania also sets distance rules for where hemp can be planted:
- No closer than 200 feet from any residential building, without prior written PDA approval.
- No closer than 1,000 feet from a pre-K through 12th grade school property or a public recreational area, without written approval.
- No closer than three miles from an approved medical marijuana growing facility.
Every lot must be sampled for THC before harvest by a PDA-certified sampling agent or PDA inspector. Growers cannot collect their own compliance samples, and harvest cannot begin until the official sample has been taken. A crop testing between 0.3% and 1.0% THC is generally treated as a non-negligent outcome if the grower made reasonable efforts to comply.4Commonwealth of Pennsylvania. Hemp Program FAQs Above 1.0%, or where the PDA finds the high levels were intentional, criminal penalties may apply.
Processing hemp (drying, trimming, extracting, or handling viable hemp material) also requires a PDA permit, with the same calendar-year cycle and background-check rules.10Commonwealth of Pennsylvania. Commonwealth of Pennsylvania – Hemp A company that only works with finished extracts or derivatives, such as a lotion maker adding CBD isolate, is in a different regulatory category and may not need a processing permit, though food and cosmetic rules still apply.
Shipping Hemp Products
Hemp and hemp-derived CBD products can be shipped domestically through USPS if they meet the federal definition of hemp and the shipper complies with all applicable federal, state, and local laws. Shippers must keep documentation establishing compliance, including lab results, licenses, or compliance reports, for at least two years after the date of mailing.11United States Postal Service. USPS Postal Bulletin – Mailability of Hemp Products International mailing through USPS is prohibited. Private carriers set their own policies, which tend to be more restrictive.
After November 2026, the shift to total THC testing and the 0.4-milligram container cap will narrow what qualifies as a mailable hemp product. Anyone shipping in volume should update COAs, licensing records, and standard operating procedures well before that deadline.
