Hybrid marijuana strains are a combination of different cannabis types. They can be Indica dominant, Sativa dominant or balanced. Their appearances and effects are heavily influenced by their parentage. For example, there can be tall Indica dominant hybrids or short Sativa dominant strains. The genetics also influence leaf shape, flowering time, yields and smell.
Cannabis Indica is a member of the Cannabaceae family. The plants have short stalk and broad leaves, when compared to Sativa plants. This type of marijuana is believed to originate from the Hindu Kush mountain range. Indicas are well-suited for cultivation in temperate climates, as Kush mountains have warm summers and very cold winters. Indica plants are mostly cultivated in India, Afghanistan, Bangladesh and Pakistan and are traditionally used in hashish production. Indica plants usually have a higher CBD rate than their Sativa relatives.
Cannabis sativa is a member of the Cannabaceae family with long stalk and narrow leaves. The species was first classified in 1753 by Carl Linnaeus. This marijuana type was cultivated for centuries for food, recreation, medicine, oil and industrial fiber. Female plant flowers are arranged in racemes and produce hundreds of seeds. Male plants discard their pollen and die a couple of weeks before seed harvest. Cannabis Sativa has higher levels of THC compared to CBD. In a day the plants need 12-13 hours of light to stay vegetative. Sativa plants take 9-15 weeks to flower, depending on environmental conditions.
Researchers are studying the effects of CBD oil and cannabis on various neuropsychiatric disorders. Authors of a 2014 review noted that CBD has anti-seizure properties and a low risk of side effects for people with epilepsy. Findings suggested that CBD may also treat many complications linked to epilepsy, such as neurodegeneration, neuronal injury, and psychiatric diseases. Another study, published in Current Pharmaceutical Design, found that CBD may produce effects similar to those of certain antipsychotic drugs, and that the compound may provide a safe and effective treatment for people with schizophrenia. However, further research is necessary.
Acne treatment is another promising use for CBD. The condition is caused, in part, by inflammation and overworked sebaceous glands in the body. A 2014 study published by the Journal of Clinical Investigation found that CBD helps to lower the production of sebum that leads to acne, partly because of its anti-inflammatory effect on the body. Sebum is an oily substance, and overproduction can cause acne. CBD could become a future treatment for acne vulgaris, the most common form of acne.
Initial research published in the Journal of Alzheimer's Disease found that CBD was able to prevent the development of social recognition deficit in participants. This means that CBD could help people in the early stages of Alzheimer's to keep the ability to recognize the faces of people that they know. This is the first evidence that CBD may slow the progression of Alzheimer's disease.
Cannabis refers to the plant Cannabis sativa. The cannabis plant originally comes from Asia. It is now grown around the world, including in Canada. Cannabis contains hundreds of chemical substances. Over 100 of these are known as cannabinoids. Cannabinoids are made and stored in the plant's trichomes. Trichomes are tiny, clear hairs that stick out from the flowers and leaves of the plant. Cannabinoids have effects on cell receptors in the brain and body. They can change how those cells behave and communicate with each other.
he most researched cannabinoid is delta-9-tetrahydrocannabinol (THC). THC is responsible for the way your brain and body respond to cannabis, including the high and intoxication. THC has some therapeutic effects but it also has harmful effects. Harmful effects may be greater when the strength of THC is higher. The potency (concentration or strength) of THC in cannabis is often shown as a percentage of THC by weight (or by volume of an oil). THC potency in dried cannabis has increased from an average of 3% in the 1980s to around 15% today. Some strains can have an average as high as 30% THC. Cannabis that contains very low amounts of THC in its flowers and leaves (less than 0.3%) is classified as hemp.
Cannabidiol (CBD) is another cannabinoid. Unlike THC, CBD does not produce a high or intoxication. There is some evidence that CBD may block or lower some of the effects of THC on the mind. This may occur when the amount of CBD in the cannabis is the same or higher than the amount of THC. CBD is also being studied for its possible therapeutic uses.
Terpenes are chemicals made and stored in the trichomes of the cannabis plant, with the cannabinoids. Terpenes give cannabis its distinctive smell.
The cannabis plant is used for its effects on the mind. It is also used for medical, social or religious purposes. Marijuana is a slang term for the dried flowers, leaves, stems and seeds of the cannabis plant. Cannabis can be taken in different ways, by:
