THC information
THC and cannabis products
Flower, concentrates, edibles and vape products are different preparations. State cannabis programs and federally approved medicines are separate regulatory contexts.

Health effects
THC can impair memory, attention and coordination. Edibles may have delayed effects; accidental ingestion by children can cause serious illness. Frequent use can lead to cannabis use disorder.
Product and dosage context
No universal cannabis dose is provided. A package’s weight does not describe its THC concentration, and a consumer cannabis product is not interchangeable with a prescribed cannabinoid medicine.
THC and cannabis are different descriptions
THC names a compound; cannabis describes plant-derived material containing many compounds. A percentage on a product label and the weight of a package are different measurements. Neither can be interpreted without knowing the actual product.
Edibles and delayed effects
Edible cannabis can have delayed and unpredictable effects compared with inhaled material. That delay can contribute to accidental overconsumption. Food-like packaging also creates risks of unintentional ingestion by children.
Cannabis use disorder and impairment
Repeated cannabis exposure can lead to problematic use in some people. Impairment of attention, memory or coordination can affect safety and daily functioning; familiarity with the product does not establish fitness to drive.
Delta-9 THC, delta-8 THC and CBD
THC isomers and CBD are different chemical descriptions. CBD does not produce the characteristic THC high, but consumer products can contain additional cannabinoids. Ingredient identity, concentration and formulation should remain separate questions.
