Strains are different variations of the cannabis plant, much like there are different variations of tomatoes: cherry, Roma, heirloom, grape, beefsteak, etc.

Each strain has a unique chemical profile, a mix of different cannabinoids and terpenes. If you like the taste, smell, and effects of a certain strain, you will likely enjoy another strain with a similar chemical profile.

The definitions of Indicas, Sativas and hybrids are somewhat fraught, Even today, budtenders and consumers the world over still use the terms “Indica,” Sativa,” and “hybrid” to refer to effects—Indicas are thought to be calm and sedating; Sativas, energetic; and hybrids, a mix of the two.

However, these terms actually refer to the plant’s physical structure, not its effects. Instead, a strain’s effects are a result of its chemical profile (its mix of cannabinoids, terpenes, and other compounds). That chemical profile will also interact with each person’s body in a different way.

While not all Sativa marijuana strains will energize you, most consumers notice a tendency for Sativas to produce a “head high,” an uplifting, stimulating effect. They also often report Sativas as being helpful in mitigating stress or anxiety, and many consumers enjoy Sativas to sharpen focus and boost creativity/motivation.

Hybrid strains are bred from both Indica- and Sativa-descended plants. Due to the long history of crossbreeding cannabis strains—much of it was historically done underground to evade authorities—strains that have pure Indica or pure Sativa lineages are rare. Most strains referred to as “Indica” or “Sativa” are, in fact, hybrids, with genetics inherited from both subspecies.

Not all Indica strains will put you “in da couch,” but nevertheless, many consumers associate Indicas with full-body effects, for example, heavy limbs or a tingly face. They also report Indicas as being helpful in aiding relaxation and curbing insomnia.
