How to choose a cannabis strain
Start with the lab report. A strain name is a label. The certificate of analysis (COA) lists cannabinoids, terpenes, and contaminant tests. Use those numbers to compare products. Do not choose by name.
Indica vs Sativa: How to Choose the Right CBD Strain
1. Check the cannabinoid ratio
Look for milligrams or percentages of THC and CBD. A product with 0.3% THC or less is hemp under US federal law. CBD-dominant products may show 10:1, 20:1, or 1:1 ratios. High-THC flower may test above 25% THC. The ratio is a stronger signal than the name.
CBD does not cause intoxication. THC does. If you want no high, choose a product with THC at or below the label limit and confirm the COA.

2. Read the terpene panel
Terpenes are aromatic compounds. Common ones include myrcene, limonene, pinene, linalool, and beta-caryophyllene. A COA may list terpene percentages. Two strains with the same THC level can differ in smell and taste. Terpene data is more useful than indica or sativa labels. Research on terpene effects in humans is limited.

3. Confirm lab testing
Look for a batch number and a test date. The COA should show cannabinoid potency, terpenes, pesticides, heavy metals, microbials, and solvents. Some states require these tests. Hemp products sold online may lack them. Ask for the COA before you buy.
4. Match dose and method
Dose depends on the product and your tolerance. In legal US markets, a common THC serving is 5 mg to 10 mg. Start with 2.5 mg to 5 mg THC if you are new. CBD doses in studies vary. Inhaled products act within minutes. Edibles can take 30 to 120 minutes. Keep the dose low on the first use.
5. Check state law
State rules differ. Some states allow recreational cannabis. Some allow medical cannabis but not recreational cannabis. Hemp-derived CBD with 0.3% THC or less is legal under US federal law, but state rules apply. Check your state before you order.
6. Keep a simple record
Write down the product name, batch number, cannabinoid ratio, dose, and time. Use the same dose twice before you change it. Stop if you feel dizzy or sick.
