Cannabis, especially the cannabinoid CBD, has also demonstrated its abilities as a powerful anti-convulsant. This property is what accounts for cannabis’ ability to reduce the severity and frequency of seizures, especially for people with epilepsy. In the United States, epilepsy is the most widely adopted qualifying condition for medical cannabis use, especially for children.

Over the ages, countless innovations have attempted to improve on the basic experience of inhaling the smoke of combusted cannabis. As a result, there are numerous ways to smoke marijuana. The rolling technique is at the root of joints, blunts, and spliffs. On the other hand, glassware and other devices are essential for smoking weed out of a pipe, bong, or bubbler.
Hemp is grown in temperate zones as an annual cultivated from seed and can reach a height of up to 5 metres (16 feet). Crops grow best in sandy loam with good drainage and require average monthly rainfall of at least 65 mm (2.5 inches) throughout the growing season. Crops cultivated for fibre are densely sowed and produce plants averaging 2–3 metres (6–10 feet) tall with almost no branching. Plants grown for oilseed are planted farther apart and are shorter and many-branched. The slender stalks are hollow except at the tip and base. The leaves are compound with palmate shape, and the flowers are small and greenish yellow. Seed-producing flowers form elongate, spikelike clusters growing on the pistillate, or female, plants. Pollen-producing flowers form many-branched clusters on staminate, or male, plants. Maximum yield and quality are obtained by harvesting soon after the plants reach maturity, indicated by the full blossoms and freely shedding pollen of the male plants. Although sometimes pulled up by hand, plants are more often cut off about 2.5 cm (1 inch) above the ground.

Although cannabis as a drug and industrial hemp both derive from the species Cannabis sativa and contain the psychoactive component tetrahydrocannabinol (THC), they are distinct strains with unique phytochemical compositions and uses.[6] Hemp has lower concentrations of THC and higher concentrations of cannabidiol (CBD), which decreases or eliminates its psychoactive effects.[6] The legality of industrial hemp varies widely between countries. Some governments regulate the concentration of THC and permit only hemp that is bred with an especially low THC content.[7][8]

Settlements which date from c. 2200–1700 BCE in the Bactria and Margiana contained elaborate ritual structures with rooms containing everything needed for making drinks containing extracts from poppy (opium), hemp (cannabis), and ephedra (which contains ephedrine).[113] Although there is no evidence of ephedra being used by steppe tribes, they engaged in cultic use of hemp. Cultic use ranged from Romania to the Yenisei River and had begun by 3rd millennium BC Smoking hemp has been found at Pazyryk.[114]
Separate levels of evidence scores are assigned to qualifying human studies on the basis of statistical strength of the study design and scientific strength of the treatment outcomes (i.e., endpoints) measured. The resulting two scores are then combined to produce an overall score. An overall level of evidence score cannot be assigned to cannabinoids because there has been insufficient clinical research. For an explanation of possible scores and additional information about levels of evidence analysis of CAM treatments for people with cancer, refer to Levels of Evidence for Human Studies of Integrative, Alternative, and Complementary Therapies.

There are hundreds of compounds in marijuana, but scientists believe the one responsible for the drugs' psychoactive effects is tetrahydrocannbinol, or THC. THC binds to cannabinoid receptors throughout the body, and marijuana's "high" comes from THC's binding to brain regions responsible for pleasure, time perception and pain, according to the National Institute on Drug Abuse (NIDA). 
An alternative to the gateway hypothesis is the common liability to addiction (CLA) theory. It states that some individuals are, for various reasons, willing to try multiple recreational substances. The "gateway" drugs are merely those that are (usually) available at an earlier age than the harder drugs. Researchers have noted in an extensive review that it is dangerous to present the sequence of events described in gateway "theory" in causative terms as this hinders both research and intervention.[259]

In his office, however, Hernandez was wary of the CBD boom. He advises well-meaning parents to think twice about voyaging into the world of over-the-counter hemp oil treatments, even if their circumstances are dire. “It’s a huge gimmick that a lot of companies are using,” Hernandez said. “You don’t know what you’re getting. ... There’s a major quality problem.”

"They nailed this story every step of the way, even when the company itself seemed to be totally clueless — or perhaps something even worse — about its own prospects," he said. "Which is why you do need to take your cue from these two gentlemen and wait until the real problems they say are solved before you get bullish. And they sure aren't there yet."
The high lipid-solubility of cannabinoids results in their persisting in the body for long periods of time.[131] Even after a single administration of THC, detectable levels of THC can be found in the body for weeks or longer (depending on the amount administered and the sensitivity of the assessment method).[131] A number of investigators have suggested that this is an important factor in marijuana's effects, perhaps because cannabinoids may accumulate in the body, particularly in the lipid membranes of neurons.[132]

Figuring out how much CBD oil to take can feel like trying to navigate through a complicated maze. The sheer volume of CBD brands on the market can create confusion for consumers, and when you take a closer look, it’s not difficult to understand why. Not only do vendors use different source materials (CBD-rich cannabis vs. industrial hemp, different strains, etc.), but they also implement different extraction techniques .
What makes CBD so appealing is that it’s non-intoxicating, so it won’t get you high, though it “is technically psychoactive, because it can influence things like anxiety,” Jikomes said. Although much of the marketing blitz around CBD centers on the fact that you can take it without getting stoned, there isn’t much research looking at the effects of CBD when used in isolation, with a couple of exceptions. One is the use of CBD to treat seizures: CBD is the active ingredient in the only cannabis product that the Food and Drug Administration has signed off on — a drug called Epidiolex, which is approved for treating two rare forms of epilepsy. Animal models and a few human studies suggest that CBD can help with anxiety, but those are the only conditions with much research on CBD in isolation.
Breeding for low THC cultivars in Europe has been reviewed by Bócsa (1998), Bócsa and Karus (1998), and Virovets (1996). Some researchers have claimed to have produced essentially THC-free strains, although at present no commercial cultivar seems to be 100% free of THC. THC content has proven to be more easily reduced in monoecious than in dioecious varieties. It should be possible to select THC-free strains, and there has been speculation that genetic engineering could be helpful in this regard. As a strategic economic and political tactic, France has been attempting for several years to have the European Union (EU) adopt legislation forbidding the cultivation of industrial hemp cultivars with more than 0.1% THC, which would mean that primarily French varieties would have to be cultivated in Europe. However, the Canadian government has found that some French material has proven to be excessively high in THC.
Cannabis was also known to the ancient Assyrians, who discovered its psychoactive properties through the Iranians.[187] Using it in some religious ceremonies, they called it qunubu (meaning "way to produce smoke"), a probable origin of the modern word "cannabis".[188] The Iranians also introduced cannabis to the Scythians, Thracians and Dacians, whose shamans (the kapnobatai—"those who walk on smoke/clouds") burned cannabis flowers to induce trance.[189]

In addition to providing useful fibers, hemp seed also has high nutritional value. and the plant can be used to make biodegradable plastics, some fuels, and a variety of other things. Hemp foods including but not limited to hemp energy bars, hemp salad dressing,hemp milk, hemp protein shakes, hemp oil gel caps and hemp protein powder are among some of the health products being produced today.

In the United States, the public's perception of hemp as marijuana has blocked hemp from becoming a useful crop and product,"[52] in spite of its vital importance prior to World War II.[53] Ideally, according to Britain's Department for Environment, Food and Rural Affairs, the herb should be desiccated and harvested towards the end of flowering. This early cropping reduces the seed yield but improves the fiber yield and quality.[54] In these strains of industrial hemp* the tetrahydrocannabinol (THC) content would have been very low.[52]
The high absorbency of hemp hurds has led to their occasional use as an absorbent for oil and waste spill cleanup. Hemp as an industrial absorbent has generated some interest in Alberta, for use in land reclamation in the oil and gas industry. Because hemp hurds are a costly product, it is likely that animal bedding will remain the most important application.
The scientific debate regarding taxonomy has had little effect on the terminology in widespread use among cultivators and users of drug-type Cannabis. Cannabis aficionados recognize three distinct types based on such factors as morphology, native range, aroma, and subjective psychoactive characteristics. Sativa is the most widespread variety, which is usually tall, laxly branched, and found in warm lowland regions. Indica designates shorter, bushier plants adapted to cooler climates and highland environments. Ruderalis is the informal name for the short plants that grow wild in Europe and Central Asia.
I have digenerative disc disease/4 bulgin discs was taking 9---10mg hydrocodones a day... i started with 3 drops of 300mg and within 5 mins started feeling better than i have theses last 6 years or so... not only that, the inflamation has decrease substantially, i wake up with energy and have begun to work out again... if im making it seem like a miracle drug... its because it is... so the first week i took 3 drops twice a day... now 3 weeks in... im taking about 5 drops 3 times a day and zero pain pills... for the first time in years i have taken control of my life agin... not depending on doctor scripts/bills etc....
