Marijuana 
Marijuana is the general term for female cannabis plants or their dried flowers. Females are distinct from male plants in that they are the ones that produce flowers which contain the high percentage of cannabinoids that hold both their medicinal and psychoactive properties.

Cannabinoids
Cannabinoids are the chemical compounds unique to cannabis that act upon the human body’s cannabinoid receptors, producing various effects including pain relief and other medically beneficial uses. Marijuana’s most well-known cannabanoid is tetrahydrocannabinol (THC) due to the fact that it is the most abundant, and also because it produces the psychoactive effects (or the “high”) that drives the plant’s recreational use. However, there are over 85 known cannabinoids all with varying effects, so THC isn’t the only one.

CBD
Cannabidiol, commonly referred to as CBD is found primarily in extractions from the hemp plant, and is often sold in gels, oils, supplements and extracts. CBD is a nonpsychoactive compound, and does not produce a ‘high’.

THC
Tetrahydrocannabinol, commonly referred to as THC is the main psychoactive compound in cannabis. While typically consumed by smoking cannabis, it is also available in oils, edibles, tinctures, capsules and more.

Cannabis
Cannabis is a plant genus that produces three species of flowering plants: Cannabis sativa, Cannabis indica, and Cannabis ruderalis. Cannabis sativa and Cannabis indica are used to produce both recreational and medical marijuana. Cannabis ruderalis is rarely farmed due to its natural lower THC content and small stature, but there is some cross-breeding thanks to ruderalis‘s unique ability to auto-flower rather than mature based on light, so there is potential for this variety to grow in popularity. Cannabis is native to Asia, but grows almost anywhere and has long been cultivated both for the production of hemp and to be used as a drug.

Sativa
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.

Indica
Indica is the less scientific name for the Cannabis indica species of cannabis. Generally these plants originated in the Middle East and Asia and include both of the famous kush and Afghan lineages. Compared to their sativa counterparts, the plants are shorter, bushier and have more compact flower structure. This species tends to produce more relaxing physical effects and can have a sedative quality.

Hash/Hash Oil
Hash is short for hashish, which is derived from cannabis plants and can be used for consumption or medication. Production involves the removal of the plant’s trichomes by sieving or filtering. Once the cannabinoid-laden powder has been collected, it is typically pressed and ready to be used. Hash ranges in potency, but is generally stronger than straight flowers since everything but the active part of the plant has been removed. A similar concentrated product can also be produced chemically using a solvent; however, this product is commonly referred to as hash oil or “honey oil.”

Heirloom
An heirloom refers to a cannabis strain that was taken from its native homeland and propagated in another geographical location.

Hemp
Hemp is a fibrous product that can be produced from the male cannabis plant and can be used in the manufacture of rope, paper, beauty products, and a vast array of other products. Hemp plants have no value as a drug since they are males.

Kief
Kief is a collected amount of trichomes that have been separated from the rest of the marijuana flower. Since trichomes are the sticky crystals that contain the vast majority of the plant’s cannabinoids, kief is known to be extremely potent. Kief is sometimes mistakenly referred to as pollen and is the primary ingredient in hashish production.

Kush
Kush refers to a line of cannabis plants that hail from the Hindu Kush mountains in Afghanistan and Pakistan. Kush strains are indicas and have a unique aroma that have given them a large fan base. Specific breeds and plants are unique, but their aroma is generally described as “earthy” and often piney combined with citrus or sweet.

Landrace
A landrace refers to a local variety of cannabis that has adapted to the environment of its geographic location. This accounts for genetic variation between landrace strains, which have been crossbred to produce the cannabis variety we see today. Landrace strains are oftentimes named after their native region, like Afghani, Thai, and Hawaiian, and traces of landraces are sometimes detectable in the names of their crossbred descendants.

Strain
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.
