The flowers of the cannabis plant are the most potent for medicinal properties. They are commonly called "buds" The leaves of the cannabis plant also contain a lower concentration of cannabinoids, The flowers and leaves of the plant can be smoked, vaporized, or used to prepare edibles.
Hash or Hashish is manufactured by separating the tiny red hairs that are on the dried cannabis flower(trichomes). The trichomes are then processed into a relatively solid paste or block. Hash can be somewhat powdery or more solid and sticky, depending on exactly how it was processed. This creates a more concentrated dose of medicine.
Also made from the trichome part of the cannabis flower is a dry powder called Kief . Kief is just the dried trichomes, without any further processing. It can be smoked or vaporized or used to make edibles. Some grinders (used to evenly cut up the cannabis flowers before vaporizing or smoking) have a small?mesh screen at the bottom for the purpose of collecting kief over time.Kief can be added to cannabis before smoking or vaporizing to increase the trichome content in the flowers.
Sativa vs. Indica
Cannabis is a genus of flowering plants that includes three putative species, Cannabis sativa, Cannabis indica, and Cannabis ruderalis. These three taxa are indigenous to Central Asia, and South Asia. Cannabis has long been used for fibre (hemp), for seed and seed oils, for medicinal purposes, and as a recreational drug.
Some species of cannabis (indica and sativa) produce the greatest amounts of a chemical known as Tetrahydrocannabinol(a cannabinoid commonly called THC). It is the THC that has the medicinal effects of marijuana as well as the psychoactive effects. The ratio of THC to CBD (Cannabidiol) determines the different types of effects. CBD has no psychotropic effects by itself(although sometimes showing a small stimulant effect, similar to caffeine),but it attenuates or reduces the higher anxiety levels caused by THC alone.
Sativa plants smell sweet and fruity and the smoke is generally quite mild. The plant Cannabis sativa is known to cause more of a "high" by stimulating hunger and by producing a rather more comedic, or energetic feeling. The effect is often characterized as uplifting and mostly cerebral. They induce a feeling of optimism and well?being, as well as providing a good measure of pain relief for certain symptoms. A few pure sativas are also very high in THC content. They are known to have a quite spacey, or hallucinogenic, effect. Sativas are a good choice for daytime medication.
Cannabis indica has a strong smelling plant with a "stinky" or "skunky" smell. The smoke of indicas is generally thick and more prone to cause coughing when inhaled. Indicas are the traditional source of hashish. Cannabis indica plant is known to cause more of a "stoned" or meditative feeling, possibly because of a higher CBD to THC ratio. Indicas strains are used more for anxiety relief and for an overall sense of calm and serenity. Cannabis indicas are also very effective for overall body pain relief, and the relaxation effect is often used in the treatment of insomnia. They are the late evening choice of many patients as an all?night sleep aid.
