Cannabis legality in the United States comes down to three things: where you are, what the product contains, and how much THC it delivers. The short answer for shoppers is that hemp-derived CBD containing no more than 0.3% delta-9 THC by dry weight is legal at the federal level under the 2018 Farm Bill, while marijuana remains a controlled substance. State law still governs what you can actually buy and have shipped to your door, so it pays to check your own state's rules before ordering.
Key Features of U.S. Cannabis Law
- Federal baseline: hemp at or under 0.3% THC is legal; marijuana is not.
- State control: each state sets its own medical, recreational, or CBD-only rules.
- THC content decides the legal category, not the plant's name or where it was grown.
- Delta-8 THC and similar compounds sit in a shifting gray area in many states.
- Age minimums of 18 or 21 apply to most hemp and cannabis purchases.
- Batch lab reports, not marketing claims, confirm a product's cannabinoid profile.
- City and county ordinances can be stricter than state law.
- Interstate shipping rules differ by destination state.
What to Check Before You Buy
Specs matter more than slogans. Look for a batch-specific certificate of analysis from an accredited lab that lists total THC, CBD, and any residual solvents or pesticides. Reputable sellers print a batch or lot number on the label that matches the report, use CO2 or ethanol extraction, and keep potency consistent from bottle to bottle. If a label says only "hemp extract" without a milligram count of CBD per serving, you have no way to verify what you are getting.
Shipping and Returns
Orders ship in plain, discreet packaging, and most shops publish a cutoff time for same-day dispatch. Because cannabis rules change quickly, a seller may decline to ship certain products to specific states and will usually note that at checkout. If a bottle arrives damaged or the batch number does not match its lab report, contact support within the stated window for a replacement or refund.

Can I legally order CBD online?
Yes in most states, provided the product meets the federal hemp definition and the seller ships to your state. Verify local limits first.
What does 0.3% THC actually mean?
It is the concentration of delta-9 THC measured on a dry-weight basis. Above that threshold, the plant or product is treated as marijuana under federal law.
