Strain Finder: How to Pick Cannabis Strains That Fit Your Needs
A strain finder filters cannabis by effects, THC, CBD, and terpenes. See how the tools work, what they miss, and how to pick a strain that fits.
What a strain finder does
A strain finder searches dispensary menus by strain name, price, THC level, package weight, and distance. Menu data comes from the retailer. Prices change during the day, so a listing you see at noon can differ at 6 p.m.
Compare cost per milligram of THC
Price per gram hides value. Divide the total price by the milligrams of THC in the package.

Example: 3.5 g of flower at 20% THC holds 700 mg of THC. At $35, that is $0.05 per mg. A 1 g pre-roll at 20% THC holds 200 mg. At $12, that is $0.06 per mg.

Add sales tax, delivery fees, and any minimum order to the total. A low sticker price can lose after those costs.

Set parameters before you search
- Weight: 1 g, 3.5 g, 7 g, or 28 g.
- THC range: 15% to 25% covers most flower listings.
- Form: flower, pre-roll, concentrate, vape, or edible.
- Delivery radius or store distance.
- Maximum price per mg of THC.
- Cultivator or brand.
Check these items on every listing
- Seller license number. State regulators publish license lists and revocation records.
- Batch lab report, also called a COA. Look for the batch ID, test date, and lab name.
- Harvest or package date. Flower loses moisture and terpenes over time.
- Total THC. Labels may list delta-9 THC and total THC as separate numbers.
- Return policy, delivery minimum, and payment methods.
Pitfalls
Prices far below the local market
A $60 ounce in a state where ounces sell for $200 needs an explanation. Ask for the license number and the batch COA. If the seller cannot produce them, stop.
Gift card, wire, and crypto payments
Licensed retailers take cash, debit, or state-approved payment apps. A request for gift card codes is a fraud pattern.
Hemp-derived THC sold across state lines
Federal law allows hemp products with delta-9 THC at or below 0.3% on a dry weight basis. State law controls the rest. Shipment rules differ by state.
Label accuracy
Published lab analyses of retail cannabis found label THC values that did not match measured THC in a share of samples. Treat a listed percentage as a range, not a fixed number.
Dosing note
Edible serving caps are set by state. Common limits are 10 mg of THC per serving and 100 mg per package. A 100 mg package sold as one unit is not one dose.
