Sativa is the less scientific name for the cannabis sativa species of cannabis plant. In general, these plants originated outside of the Middle East and Asia and include strains that are from areas such as South America, the Caribbean, Africa, and Thailand. These strains tend to grow taller as plants (usually over 5 feet), are lighter in color and take longer to flower. When consumed, sativas tend to produce more cerebral effects as opposed to physical and sedative ones.
Shatter or ice are terms used to refer to BHO.
A strain is a specific variety of a plant species. Strains are developed to produce distinct desired traits in the plant and are usually named by their breeders (or by creative consumers). Strain names often reflect the plant's appearance, its promised buzz, or its place of origin. Although the medical marijuana industry strives for consistency, strains can easily be mistakenly or purposely misidentified.
