Last year, the Hemp Industries Association (HIA) estimated the total retail value of all hemp products sold in the U.S. at $620 million. Sadly, all of the raw hemp materials were imported from other countries. (More on that later.) Hemp is an attractive rotation crop for farmers. As it grows, hemp breathes in CO2, detoxifies the soil, and prevents soil erosion. What’s left after harvest breaks down into the soil, providing valuable nutrients.
The Department has policies and procedures in place for the commonwealth's hemp research program, which can be found in the 2019 Pilot Program Parameters. Researchers from institutions of higher education or growers who would like to be considered for participation in the 2019 program must submit a 2019 PDA Industrial Hemp Research Pilot Program Permit Application prior to the application deadline of December 17, 2018. Researchers who participated in the 2018 Pilot Program may submit a Permit Renewal form by December 17, 2018 to continue their projects in the 2019 growing season.

For example, the six hemp oil companies the FDA had investigated in February had explicitly advertised CBD products for use in the “cure, mitigation, treatment, or prevention of diseases.” The agency sent warning letters to the companies, ordering them to change their product labeling or face potential legal action. Then, in May, the FDA announced it was excluding products containing cannabidiol from its definition of dietary supplements altogether. Hard, the spokesman for Medical Marijuana, Inc., said the company views “these developments as positive because this allows the debate regarding CBD to come to the forefront.” He characterized the FDA’s May announcement as “an opinion” and added, “Medical Marijuana, Inc. and HempMeds, along with industry associations, are working on determining how we can come to a mutual understanding on the matter with the FDA.”
When privacy isn’t a requirement, outdoor cannabis grows can provide many advantages over indoor operations. Sunlight is the single most important factor for successful outdoor marijuana growing. It’s important to choose a plot with total sunshine throughout the day. Therefore, cannabis growers in the northern hemisphere will want plots with southern exposure, exposing marijuana plants to the sun’s arc across the sky.
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]

The word cannabis is from Greek κάνναβις (kánnabis) (see Latin cannabis),[134] which was originally Scythian or Thracian.[135] It is related to the Persian kanab, the English canvas and possibly even to the English hemp (Old English hænep).[135] In modern Hebrew, קַנַּבּוֹס‬ qannabōs (modern pronunciation: [kanaˈbos]) is used but there are those who have theorized that it was referred to in antiquity as קני בושם q'nei bosem, a component of the biblical anointing oil.[136][137] Old Akkadian qunnabtu, Neo-Assyrian and Neo-Babylonian qunnabu were used to refer to the plant meaning "a way to produce smoke".[138][139][140]
According to the United Nations Office on Drugs and Crime (UNODC), "the amount of THC present in a cannabis sample is generally used as a measure of cannabis potency."[149] The three main forms of cannabis products are the flower, resin (hashish), and oil (hash oil). The UNODC states that cannabis often contains 5% THC content, resin "can contain up to 20% THC content", and that "Cannabis oil may contain more than 60% THC content."[149]

^ Jump up to: a b c This paper begins with a history of hemp use and then describes how hemp was constructed as a dangerous crop in the U.S. The paper then discusses the potential of hemp as an alternative crop. Luginbuhl, April M. (2001). "Industrial hemp (Cannabis sativa L): The geography of a controversial plant". The California Geographer (PDF). 41. California Geographical Society. pp. 1–14. Retrieved 2013-03-28. Hemp contains less than 1% THC, or tetrahydrocannabinols, the psychoactive property in marijuana. In other words, smoking hemp cannot create a 'high.' ... The dense growth of hemp eliminates other weeds.... The best growing technique for hemp, planting 300 to 500 plants per square meter, also helps authorities easily tell the hemp from marijuana, which is a plant that is less densely cultivated. (Roulac 1997; 149).

The main difference between the two is in its chemical composition, specifically in tetrahydrocannabinol (THC). THC is the chemical responsible marijuana’s psychological effects.An average batch of marijuana contains anywhere from 5-20% THC content. Some premium marijuana can have up to 25-30% THC. Hemp, on the other hand, has a max THC level of 0.3%, essentially making it impossible to feel any psychoactive effect or get a “high”. This threshold is heavily regulated in other countries that have legalized hemp.Hemp also has high cannabidiol (CBD) content that acts as THC’s antagonist, essentially making the minimal amount of THC useless.
Side effects of CBD include sleepiness, decreased appetite, diarrhea, fatigue, malaise, weakness, sleeping problems, and others.[3] It does not have intoxicating effects like those caused by THC, and may have an opposing effect on disordered thinking and anxiety produced by THC.[7][10][11] CBD has been found to interact with a variety of different biological targets, including cannabinoid receptors and other neurotransmitter receptors.[7][12] The mechanism of action of CBD in terms of its psychoactive and therapeutic effects is not fully clear.[7]

One of the biggest players in this new industry is Medical Marijuana, Inc., a company formed in 2009 that operates out of Poway, California, just north of San Diego. It has played a leading role in the so-called Green Rush, as businesses have moved quickly to capitalize on the gradual legalization of marijuana for medical and recreational purposes by states across the country. The company’s spokesman, Andrew Hard, boasted that Medical Marijuana, Inc., “created the CBD industry and was first to market with CBD products.” Through its various subsidiaries, Medical Marijuana, Inc. sells some of the most recognizable products on the cannabis market— everything from Cibaderm CBD-infused shampoo to CanChew chewing gum. In 2014, the company generated $14.5 million in revenue.
Most human studies of CBD have been done on people who have seizures, and the FDA recently approved the first CBD-based drug, Epidiolex, for rare forms of epilepsy. Clinical trials for other conditions are promising, but tiny. In one Brazilian study published in 2011 of people with generalized social anxiety disorder, for example, taking a 600-mg dose of CBD (higher than a typical dose from a tincture) lessened discomfort more than a placebo, but only a dozen people were given the pill.
Did you get an answer for this? I have the exact same scenario. I'm treating my TN with Tegretol, and recently tried CBD. I think I took too much and there are some weird drug interactions with Tegretol and I felt quite stoned....was alone and talking to myself in my head thinking I was Einstein. It freaked me out a bit but I think I took too much. I'm trying lower doses again as recently my TN seems to be resisting the meds, although I have had a lot of emotional stress, which seems to be a trigger. Thanks!! Anna
