There is no national number. Cannabis possession limits in the US come from state law, so the answer to "near me" is really "in my state, and sometimes in my city." A legal ounce in one state is a misdemeanor twenty minutes down the highway. Some states allow adults to carry one or two ounces, some allow more at home than in public, and a handful still treat any amount as a criminal matter. Before you buy, carry, or travel, pull up your own state's statute rather than a blog summary.

Why the limit changes by ZIP code
Three things vary from state to state, and they do not line up neatly. First, whether cannabis is legal at all for adults, medical patients only, or not legal. Second, the quantity threshold: most adult-use states land somewhere between one and three ounces of flower, but concentrates and edibles are counted differently. Third, local rules. A city or county can restrict possession in parks, on beaches, or in vehicles even when the state says yes. I check the state statute first, then the city code if I plan to be somewhere specific.
The 0.3% THC line matters for CBD shoppers
Hemp is defined federally as cannabis with no more than 0.3% delta-9 THC on a dry weight basis, and the 2018 Farm Bill removed hemp from the Controlled Substances Act. That is a federal rule. It does not override your state's rules on hemp-derived products, and several states have added their own caps on THC per serving, per package, or per product type. A broad-spectrum tincture with trace THC may be fine at your kitchen table and restricted in a state you are driving through. If you buy online, check the destination state, not just the shipping origin.
What to check before you carry anything
- The possession section of your state's criminal or health code, not a dispensary FAQ
- Whether the limit is written in ounces of flower, grams of concentrate, or total product weight
- Public versus private limits. Several states are more generous at home
- Medical cardholder rules, which are often separate and higher
- City and county ordinances for parks, festivals, and vehicles
- Hemp-specific rules from your state department of agriculture
Reading a limit correctly
An ounce is not always an ounce. Many states define usable cannabis by weight of flower, so an ounce of oil, wax, or a gummy does not translate to the same allowance. Some statutes count the whole product weight, packaging aside. Others apply a separate, smaller cap to concentrates. Read the definition section of the statute alongside the limit, because that is where these distinctions live. When a number sounds generous, check what it is a number of.

Traveling with CBD or cannabis
Crossing a state line resets the rules entirely, even between two legal states. Federal law still treats cannabis as controlled, and transporting it across state lines is a federal issue regardless of what either state allows. For hemp-derived CBD, TSA rules track the federal hemp definition, but that says nothing about the law at your destination. Check the destination state's hemp and cannabis rules before you pack.
Where I start looking
The state legislature's own website, searching the code for "possession" and "cannabis" or "marihuana." Then the state agriculture department for hemp product rules. National advocacy summaries are useful as a cross-check, but they lag behind amendments, so I read the statute text last and trust it most. None of this is legal advice. If the amount or the product matters to your livelihood, ask a licensed attorney in your state.
