The pick
Buy by chemotype. Chemotype means the measured THC level, CBD level, and terpene list on the batch lab report. The words indica and sativa do not appear on a lab report. A jar labeled sativa can test at 28% THC and 0.4% terpinolene. A jar labeled indica can test at 19% THC and 1.1% limonene. Both sit on the same shelf. The jar label does not tell you which one will feel sedating.
what is the difference between indica and sativa
Where the labels come from
Carl Linnaeus named the species Cannabis sativa in 1753. Jean-Baptiste Lamarck described Cannabis indica in 1785 from plants collected in India. Growers then split the crop by plant shape.
indica vs sativa vs hybrid differences
- Sativa: tall plants, narrow leaflets, long flowering time, origin near the equator.
- Indica: short plants, broad leaflets, short flowering time, origin in Afghanistan, Pakistan, and northern India.
- Ruderalis: short auto-flowering plants from central Asia, low THC.
- Hybrid: a cross of any two. Breeders have crossed these groups for 50 years.
Plant shape is a growth trait. It is not a chemical trait.
What the labs measure
Tests of retail flower show a weak link between the label and the chemistry. THC content runs from about 15% to 30% in most US flower. CBD flower runs from about 10% to 20%. Total terpenes sit near 0.5% to 3% by weight. The common terpenes are myrcene, limonene, pinene, caryophyllene, linalool, and terpinolene.
which is stronger indica or sativa
Two batches of the same cultivar can test apart. Light, harvest week, cure, and storage move the numbers. A batch lab report matters more than the cultivar name.
How to choose, in order
- Ask for the COA, the certificate of analysis, for the batch in the jar.
- Read THC %, CBD %, and total terpenes.
- Read the top three terpenes.
- Buy the smallest size: a 1 g, a pre-roll, or a 3.5 g jar.
- Log onset, peak, and duration. Note body feel or head feel. Wait two hours before you judge.
- Buy the next jar from the numbers, not the label.
Options
High-THC hybrid
THC 20% to 30%, CBD under 1%. Common terpenes: caryophyllene, limonene, myrcene. Pick this for a strong THC effect and no CBD. Start with one or two puffs.
High-CBD flower
CBD 10% to 20%, THC under 0.3% to 1%. Pick this for little or no intoxication. Hemp flower sold under federal law sits at THC 0.3% or less.
Balanced 1:1
THC near CBD by weight. Pick this for a milder THC effect. The ratio shifts batch to batch. Read the COA.
Terpinolene or pinene forward
These terpenes show up in batches sold as sativa. Reports of an alert effect come from user surveys, not controlled trials. Data here is thin.
Myrcene forward
Myrcene shows up in batches sold as indica. Reports of sedation carry the same limit: user surveys, not trials.
Limits of the evidence
No US federal standard defines indica, sativa, or hybrid. State labeling rules differ. Clinical data on terpenes and mood is limited. Treat the label as a marketing term and the COA as the data.
Cannabis impairs driving and reaction time. Keep it away from children and pets. Do not use if pregnant or breastfeeding.
