What to prepare before your first order
Online cannabis sales in the United States run through licensed dispensaries, and the rules change at every state line. Delivery may be legal in one state and banned in the next. Before you shop, confirm that adult-use or medical sales are legal where you live and that the retailer holds a current retail or delivery license. Federal law still treats cannabis as illegal, so no licensed US shop ships across state lines.
- A government photo ID showing you are 21 or older, or 18+ with a valid medical card in states that allow it.
- An address inside the shop's licensed delivery zone.
- A payment method the store accepts. Most licensed shops take debit or cash on delivery.
- A spending limit and a rough plan for how much you will use in a month.
How to buy cannabis online, step by step
- Confirm adult-use or medical sales are legal in your state and your city has not banned delivery.
- Find the shop's license number on its site, then look that number up in your state cannabis regulator's public licensee list.
- Create an account and upload your ID for age verification.
- Open the menu listing for each product and note the THC percentage, CBD percentage, package weight, and price.
- Pull the certificate of analysis for the batch and check it for pesticides, mold, heavy metals, and solvent residue.
- Pick a beginner-friendly format such as a low-dose edible, a 1:1 THC to CBD tincture, or a low-potency flower.
- Read the label math. A 100 mg chocolate bar cut into 10 pieces gives you 10 mg per piece.
- Add items to the cart and check the order minimum.
- Review the full total: subtotal, excise tax, sales tax, delivery fee, and tip.
- Choose a delivery window or a pickup time that fits your schedule.
- Pay only through the methods the licensed shop lists on its own checkout page.
- At handoff, match the package seal, batch number, and expiration date against your receipt.
- Store everything in a locked container away from children and pets.
Parameters worth comparing
Potency is the number that matters most for a beginner. Five milligrams of THC is a standard starting dose for edibles, and the effect can take 30 to 120 minutes to appear. Smoking and vaping hit within minutes, which makes them easier to pace but harder to dose precisely. Per-transaction purchase caps, delivery radius, minimum order size, and whether the shop publishes lab results all separate serious retailers from weak ones.
Pitfalls to avoid
- Sites with no license number and no state registry match.
- Shops that bundle a free "gift" with a paid item to dodge sales rules.
- Sellers who demand payment by gift card, crypto, or a peer-to-peer transfer with no buyer protection.
- Listings with no certificate of analysis or a COA that names a different product.
- Prices far below local market rates, which usually signal untested product.
- Social media accounts that take orders through direct messages.
- Delivery without an ID check at the door. Licensed couriers always verify age.
