It was controversial to pursue medical marijuana for such a young patient, but when they gave Charlotte oil extracted from high-CBD cannabis, her seizures stopped almost completely. Instead of moving, other families obtained CBD oil through the illegal distribution networks. If Epidiolex wins approval it would be the first time the agency approves a drug derived from the marijuana plant. Epidiolex was developed by the London-based GW Pharmaceuticals , which grows cannabis on tightly controlled farms in the UK.
While parents treating their children with CBD had to proceed based on trial and error, like a folk medicine, they also had to wonder whether dispensary purchased CBD was professionally manufactured and contained what the package said it did. GW brought a scientific understanding and pharmaceutical grade manufacturing to this promising compound. The company is also studying cannabinoid-based drugs as a treatment for autism spectrum disorders, an aggressive brain tumor called glioblastoma, and schizophrenia.
Other industries, not subject to the strict regulations governing pharmaceuticals are eager to develop their own CBD products, everything from joints and vape pens to skin creams and edibles which may or may not have valid medical use. Withdrawal symptoms are rarely a problem with controlled medical administration of cannabinoids. The ability to drive vehicles or to operate machinery may be impaired until a tolerance is developed.
Acute effects may include anxiety and panic, impaired attention, and memory while intoxicated , an increased risk of psychotic symptoms, and possibly increased risk of accidents if a person drives a motor vehicle while intoxicated. There have been few reports of symptoms lasting longer. According to the United States Department of Health and Human Services , there were , emergency room visits associated with cannabis use in These statistics include visits in which the patient was treated for a condition induced by or related to recent cannabis use.
The drug use must be "implicated" in the emergency department visit, but does not need to be the direct cause of the visit. Most of the illicit drug emergency room visits involved multiple drugs. Effects of chronic use may include bronchitis , a cannabis dependence syndrome, and subtle impairments of attention and memory. These deficits persist while chronically intoxicated. There has been a limited amount of studies that have looked at the effects of smoking cannabis on the respiratory system.
Cannabis smoke contains thousands of organic and inorganic chemical compounds. This tar is chemically similar to that found in tobacco smoke,  and over fifty known carcinogens have been identified in cannabis smoke,  including nitrosamines, reactive aldehydes, and polycylic hydrocarbons, including benz[a]pyrene.
Evidence for causing these cancers is mixed concerning heavy, long-term use. In general there are far lower risks of pulmonary complications for regular cannabis smokers when compared with those of tobacco.
There is serious suspicion among cardiologists, spurring research but falling short of definitive proof, that cannabis use has the potential to contribute to cardiovascular disease. If cannabis arteritis turns out to be a distinct clinical entity, it might be the consequence of vasoconstrictor activity observed from deltaTHC and deltaTHC. Research in these events is complicated because cannabis is often used in conjunction with tobacco, and drugs such as alcohol and cocaine.
Cannabis usually causes no tolerance or withdrawal symptoms except in heavy users. In a survey of heavy users The rate goes up to one in six among those who begin use as adolescents, and one-quarter to one-half of those who use it daily according to a NIDA review. A literature review found that exposure to marijuana had biologically-based physical, mental, behavioral and social health consequences and was "associated with diseases of the liver particularly with co-existing hepatitis C , lungs, heart, and vasculature".
A systematic review evaluated published studies of the acute and long-term cognitive effects of cannabis. THC intoxication is well established to impair cognitive functioning on an acute basis, including effects on the ability to plan, organize, solve problems, make decisions, and control impulses.
The extent of this impact may be greater in novice users, and paradoxically, those habituated to high-level ingestion may have reduced cognition during withdrawal.
Studies of long-term effects on cognition have provided conflicting results, with some studies finding no difference between long-term abstainers and never-users and others finding long-term deficits.
The discrepancies between studies may reflect greater long-term effects among heavier users relative to occasional users, and greater duration of effect among those with heavy use as adolescents compared to later in life. Exposure to THC can cause acute transient psychotic symptoms in healthy individuals and people with schizophrenia. A meta analysis concluded that cannabis use reduced the average age of onset of psychosis by 2. The genus Cannabis contains two species which produce useful amounts of psychoactive cannabinoids: Cannabis indica and Cannabis sativa , which are listed as Schedule I medicinal plants in the US;  a third species, Cannabis ruderalis , has few psychogenic properties.
The most psychoactive cannabinoid found in the cannabis plant is tetrahydrocannabinol or deltatetrahydrocannabinol, commonly known as THC. CB1 and CB2 are the primary cannabinoid receptors responsible for several of the effects of cannabinoids, although other receptors may play a role as well.
CB1 receptors are found in very high levels in the brain and are thought to be responsible for psychoactive effects. The low bioavailability is largely attributed to significant first-pass metabolism in the liver and erratic absorption from the gastrointestinal tract. Due to the poor bioavailability of oral preparations, alternative routes of administration have been studied, including sublingual and rectal. These alternative formulations maximize bioavailability and reduce first-pass metabolism.
Like cannabinoid absorption, distribution is also dependent on route of administration. Smoking and inhalation of vaporized cannabis have better absorption than do other routes of administration, and therefore also have more predictable distribution. It distributes rapidly to highly vascularized organs such as the heart, lungs, liver, spleen, and kidneys, as well as to various glands.
Low levels can be detected in the brain, testes, and unborn fetuses, all of which are protected from systemic circulation via barriers. DeltaTHC is the primary molecule responsible for the effects of cannabis. Ingestion of edible cannabis products lead to a slower onset of effect than the inhalation of it because the THC travels to the liver first through the blood before it travels to the rest of the body.
Inhaled cannabis can result in THC going directly to the brain, where it then travels from the brain back to the liver in recirculation for metabolism. Smoking has been the means of administration of cannabis for many users, but it is not suitable for the use of cannabis as a medicine. The US Food and Drug Administration FDA has not approved smoked cannabis for any condition or disease, as it deems that evidence is lacking concerning safety and efficacy.
Since ancient humans used hemp seed as food, it was quite natural for them to also discover the medicinal properties of the plant. He recommended the substance for many ailments, including constipation, gout, rheumatism, and absent-mindedness.
The Ebers Papyrus c. Surviving texts from ancient India confirm that cannabis' psychoactive properties were recognized, and doctors used it for treating a variety of illnesses and ailments, including insomnia, headaches, gastrointestinal disorders, and pain, including during childbirth. The Ancient Greeks used cannabis to dress wounds and sores on their horses,  and in humans, dried leaves of cannabis were used to treat nose bleeds, and cannabis seeds were used to expel tapeworms.

Cannabis seeds may have been used for food, rituals or religious practices in ancient Europe and China. Widely cultivated strains of cannabis, such as "Afghani" or "Hindu Kush", are indigenous to the Pakistan and Afghanistan regions, while "Durban Poison" is native to Africa.
The use of cannabis in medicine began to decline by the end of the 19th century, due to difficulty in controlling dosages and the rise in popularity of synthetic and opium -derived drugs.
In the United States, the medical use of cannabis further declined with the passage of the Marihuana Tax Act of , which imposed new regulations and fees on physicians prescribing cannabis. Pharmacopeia in , and officially banned for any use with the passage of the Controlled Substances Act of Cannabis began to attract renewed interest as medicine in the s and s, in particular due to its use by cancer and AIDS patients who reported relief from the effects of chemotherapy and wasting syndrome.
The use of cannabis, at least as fiber, has been shown to go back at least 10, years in Taiwan. In Mexico , THC content of medical cannabis is limited to one percent. Article 2 provides for the following, in reference to Schedule IV drugs:. A Party shall, if in its opinion the prevailing conditions in its country render it the most appropriate means of protecting the public health and welfare, prohibit the production, manufacture, export and import of, trade in, possession or use of any such drug except for amounts which may be necessary for medical and scientific research only, including clinical trials therewith to be conducted under or subject to the direct supervision and control of the Party.
The convention thus allows countries to outlaw cannabis for all non-research purposes but lets nations choose to allow use for medical and scientific purposes if they believe total prohibition is not the most appropriate means of protecting health and welfare. The convention requires that states that permit the production or use of medical cannabis must operate a licensing system for all cultivators, manufacturers, and distributors and ensure that the total cannabis market of the state shall not exceed that required "for medical and scientific purposes".
In the United States, the use of cannabis for medical purposes is legal in 33 states, four out of five permanently inhabited U. In December , however, the Rohrabacher—Farr amendment was signed into law, prohibiting the Justice Department from prosecuting individuals acting in accordance with state medical cannabis laws. The method of obtaining medical cannabis varies by region and by legislation.
In the US, most consumers grow their own or buy it from cannabis dispensaries in states where it is legal. In the United States, health insurance companies may not pay for a medical marijuana prescription as the Food and Drug Administration must approve any substance for medicinal purposes.
Before this can happen, the FDA must first permit the study of the medical benefits and drawbacks of the substance, which it has not done since it was placed on Schedule I of the Controlled Substances Act in Therefore, all expenses incurred fulfilling a medical marijuana prescription will possibly be incurred as out-of-pocket.
Organizations that have issued statements in opposition to the legalization of medical cannabis include the American Academy of Pediatrics ,  American Psychiatric Association ,  and American Society of Addiction Medicine.
The American Medical Association  and American College of Physicians  do not take a position on the legalization of medical cannabis, but have called for the Schedule I classification of cannabis to be reviewed. The American Academy of Family Physicians similarly does not take a position, but does support rescheduling in order to facilitate research.
As an antiemetic , these medications are usually used when conventional treatment for nausea and vomiting associated with cancer chemotherapy fail to work. Nabiximols is used for treatment of spasticity associated with MS when other therapies have not worked, and when an initial trial demonstrates "meaningful improvement". Relative to inhaled consumption, peak concentration of oral THC is delayed, and it may be difficult to determine optimal dosage because of variability in patient absorption.
In , Albert Lockhart and Manley West began studying the health effects of traditional cannabis use in Jamaican communities. They developed, and in gained permission to market, the pharmaceutical "Canasol", one of the first cannabis extracts. Medical cannabis research includes any medical research on using cannabis as a treatment for any medical condition. For reasons including increased popular support of cannabis use, a trend of cannabis legalization , and the perception of medical usefulness, more scientists are doing medical cannabis research.
