Sygdomme og Cannabinoider

SYGDOMME, CANNABIS OG BIVIRKNINGER
GENERELLE BEMÆRKNINGER

Generelt er CBD bemærkelsesværdigt sikkert sammenlignet med næsten alle konventionelle lægemidler. CBD har ingen fatale bivirkninger, den mest almindelige bivirkning er mundtørhed. CBD er meget antiinflammatorisk og fungerer som et antipsykotisk molekyle.

Kliniske studier med enkelt cannabinoider eller hele plantepræparater (røget cannabis, cannabisekstrakt) har ofte været inspireret af positive anekdotiske oplevelser hos patienter, der anvender rå cannabisprodukter. Det antiemetiske, appetitforbedrende, afslappende virkning, analgesi og terapeutisk anvendelse i Tourettes syndrom blev alle opdaget på denne måde.

I betragtning af det stigende bevis for det terapeutiske potentiale for forskellige cannabinoider er det vigtigt at skelne mellem medicinsk brug af produkter, der er rige på THC, og dem, der er rige på CBD, som er en ikke-psykoaktiv ingrediens i cannabis.

Der er ingen død på grund af cannabis og praktisk taget ingen bivirkninger forbundet med CBD, dem der er blevet registreret med Epidiolex: (sammen med andre lægemidler)

  • Tør mund
  • Døsighed
  • Nedsat appetit
  • Nedsat appetit
  • Diarré
  • Transaminase forhøjelser
  • Træthed
  • Ubehag (utilpashed)
  • Svaghed / sløvhed
  • Udslæt
  • Vanskelighedsvanskeligheder (søvnløshed, forstyrret søvn og dårlig søvnkvalitet)

I Danmark er der rapporteret om 21 bivirkninger i løbet af forsøgets første år, 5 (4 Bedrocan, 1 dråber Stenocare) blev anset for alvorlige. I de fleste tilfælde overdoseres mennesker. 1800 patienter fik deres medicinske cannabis fra lægen i samme periode.

GENERELLE BEMÆRKNINGER (BIVIRKNINGER)

Dødsfald på grund af cannabisbrug kendes ikke. Den gennemsnitlige dødelige dosis hos rotter var 800 til 1.900 mg (afhængig af stammen) oral THC pr. Kg legemsvægt. I studier med aber blev der ikke registreret nogen dødsfald efter de højest anvendte doser på 9.000 mg / kg oral THC. Alle mulige bivirkninger er dosisafhængige. Terapi skal starte med lave doser, langsomt stigende, så den individuelle dosis kan bestemmes, og uønskede effekter kan undgås.

Læge Tina Ingrid Horsted: “Vores undersøgelse viser, at medicinsk cannabis er et harmløst alternativ til traditionelle smertestillende midler. De fleste havde milde bivirkninger i form af mental og fysisk træthed”. Tina har ikke oplevet, at nogen af ​​sine patienter er afhængige af cannabis som medicin. Men de er afhængige af morfin. (+400.000 danskere på morfin, de 40.000 er afhængige) Hun anslår, at ca. 10-20% af danskerne har forsøgt at selvmedicinere cannabis – enten ved at ryge eller tage olien.

AKUTE BIVIRKNINGER

Kendte psykiske bivirkninger er sedation, eufori (“høj”), dysfori, frygt for at dø, følelse af at miste kontrol, nedsat hukommelse, ændret tidsopfattelse, depression, hallucinationer. I tilfælde af stærke psykiske bivirkninger skal de berørte bringes til et roligt sted og “tales ned”. Kognitiv og psykomotorisk præstation dæmpes. En diskret reduktion af psykomotorisk ydeevne kan observeres op til 24 timer efter administration af THC.

Hyppige akutte fysiske bivirkninger er mundtørhed, bevægelsesforstyrrelse, muskelsvaghed, sløret tale, stigning i hjerterytmen, fald i blodtrykket i lodret position, til sidst med svimmelhed. I tilfælde af svimmelhed skal den berørte lægge sig. I vandret position kan et lidt højere blodtryk måles. Sjældne bivirkninger er kvalme og hovedpine.

Alle akutte bivirkninger er dosisafhængige og forsvinder generelt inden for timer eller 1-3 dage uden specifik behandling.

Cannabis (THC) har et potentiale for afhængighed. Afhængighed er muligvis ikke et relevant problem inden for rammerne af terapi af sygdomme, men tilbagetrækning kan være uønsket. Tilbagetrækning er ikke beskrevet hos patienter, der var langvarigt behandlet med THC. Men tilbagetrækning er blevet observeret hos fritidsbrugere. Dermed kan der forekomme psykiske symptomer (angst, rastløshed, søvnløshed) og fysiske symptomer (spyt, diarré). Forløbet af en psykose kan påvirkes ugunstigt. Usårbare personer, der begynder med en psykose, kan fremskyndes eller udløses.

ALZHEIMERS

Clinical studies have shown that cannabis may not only increase appetite in patients with Alzheimer’s disease but also reduce disturbed behavior and agitation. A small study reported that cannabis oil was effective in treating symptoms of dementia patients, including agitation/aggression, irritability, apathy, sleep, and caregiver distress.

An appetite enhancing the effect of THC is observed with daily divided doses totaling 5 mg. When required, the daily dose may be increased to 20 mg. In a long-term study of 94 AIDS patients, the appetite-stimulating effect of THC continued for months, confirming the appetite enhancement noted in a shorter 6-week study. THC doubled appetite on a visual analog scale in comparison to placebo. Patients tended to retain a stable body weight over the course of seven months. A positive influence on body weight was also reported in 15 patients with Alzheimer’s disease who were previously refusing food. In addition, cannabis products can improve appetite in cancer patients and in chronic obstructive pulmonary disease (COPD). A study, with a small sample size, points to the potential of THC for improvement of symptoms associated with Anorexia Nervosa.

ASTHMA

Experiments examining the anti-asthmatic effect of THC or cannabis date mainly from the 1970s, and are all acute studies. The effects of a cannabis cigarette (2% THC) or oral THC (15 mg), respectively, approximately correspond to those obtained with therapeutic doses of common bronchodilator drugs (salbutamol, isoprenaline). Since inhalation of cannabis products may irritate the mucous membranes, oral administration or another alternative delivery system would be preferable. Very few patients developed bronchoconstriction after inhalation of THC.

DEPENDENCY AND WITHDRAWAL

According to historical and modern case reports cannabis is a good remedy to combat withdrawal in dependency on benzodiazepines, opiates and alcohol. For this reason, some have referred to it as a gateway drug back. In this context, both the reduction of physical withdrawal symptoms and stress connected with the discontinuance of drug abuse may play a role in its observed benefits. In addition, a small study suggests that CBD may be helpful in the treatment of tobacco dependency

ENDOCANNABINOID SYSTEM AND ENDOCANNABINOID DEFICIENCY

FIBROMYALGIA

Fibromyalgia is a painful condition affecting mostly women. While doctors don’t know much about the condition, some researchers believe it could be related to an endocannabinoid deficiency.

Studies suggest that cannabinoids can reduce pain that is similar to the pain of fibromyalgia. Other studies have shown that blocking cannabinoid receptors results in pain — meaning that an endocannabinoid deficiency could potentially cause pain like in fibromyalgia.

Additionally, many people report that the cannabinoids in marijuana are helpful as a treatment for fibromyalgia.

MIGRAINES

Migraine headaches are extremely painful and can often disable a patient for days at a time.

Migraines are associated with changes in the neurotransmitter serotonin. The endocannabinoid system and the serotonin system are
strongly linked, leading researchers to propose that migraines result from an endocannabinoid deficiency.

Researchers believe cannabis could be an effective treatment for migraine, because it has a unique set of effects on the brain that make it an “ideal treatment” for the condition.

IRRITABLE BOWEL SYNDROME

IBS is a condition that causes diarrhea, constipation, and abdominal pain. It is surprisingly common, with estimates that it affects around 15% of the population. Cannabinoid receptors are expressed in the gut, and function to regulate gastrointestinal motility, or how fast food moves through the intestines. Symptoms of IBS are related to motility that is either too fast in the case of diarrhea, or too slow in the case of constipation.

Marijuana is often used as a treatment for IBS symptoms, and has been used to treat diarrheal illness such as cholera in the past. While there are not many studies on the link between the endocannabinoid system and IBS, researchers believe endocannabinoid deficiency theory could help explain the disorder.

PTSD

A 2013 study found that endocannabinoid levels were reduced in PTSD patients, but not controls. The researchers measured blood levels of 2-AG and anandamide in people closely affected by the 9/11 attacks on the World Trade Center. They found that 2-AG levels were significantly reduced in those who met diagnostic criteria for PTSD, but not in those who did not.

This supports the theory that PTSD could be related to a clinical endocannabinoid deficiency.

EPILEPSY

The use in epilepsy is among its historically oldest indications of cannabis. Animal experiments provide evidence of the antiepileptic effects of some cannabinoids. The anticonvulsant activity of phenytoin and diazepam have been potentiated by THC. According to a few cases reports from the 20th century, some epileptic patients continue to utilize cannabis to control an otherwise unmanageable seizure disorder. Cannabis use may occasionally precipitate convulsions. A few studies showed that the use of CBD-enriched extracts by children and adolescents with intractable epilepsy yielded a positive effect on seizure load. Improvement in other symptoms, such as behavior, communication, motor skills and language, were also observed.

FIBROMYALGIA

Research shows that cannabinoids – the active compounds present in the cannabis plant – can have a beneficial effect on fibromyalgia symptoms by reducing pain and improving sleep quality. Although cannabis has not been established as an approved medicine for this medical condition, surveys indicate that fibromyalgia patients already self-medicate using cannabis. Moreover, some patients have reported cannabis to produce fewer side-effects than the available conventional treatments and, most importantly, to be effective.

GATEWAY THEORY

GLAUCOMA

In 1971, during a systematic investigation of its effects in healthy cannabis users, it was observed that cannabis reduces intraocular pressure. In the following 12 years, a number of studies in healthy individuals and glaucoma patients with cannabis and several natural and synthetic cannabinoids were conducted. Cannabis decreases intraocular pressure by an average of 25-30%, occasionally up to 50%.

Some non-psychotropic cannabinoids, and to a lesser extent, some non-cannabinoid constituents of the hemp plant also decrease intraocular pressure. While in most western countries there are other medications for intraocular pressure that are available to patients, in other parts of the world this may not be the case.

INFLAMMATORY BOWEL DISEASE AND IRRITABLE BOWEL SYNDROME

Following the rationale that the endocannabinoid system is involved with immunity and inflammation, several studies have shown that cannabis may have a therapeutic effect for treatment of patients with Inflammatory Bowel disease (Crohn’s disease and ulcerative colitis). Studies demonstrated that cannabis-based products, especially with THC content, were able to improve clinical outcomes of patients, including appetite stimulation, weight gain, reduction of pain and significant improvement in disease activity. Some patients achieved remission of the disease, and other were able to reduce the consumption of medications, such as steroids.

One study demonstrated a therapeutic effect of oral THC (dronabinol) for specific sub-groups of patients with irritable Bowel disease (IBS-D and IBS-A), and showed improved colonic compliance and motility.

MS

In many clinical trials of THC, nabilone and cannabis, a beneficial effect on spasticity caused by multiple sclerosis or spinal cord injury have been observed. Among other positively influenced symptoms were the pain, paraesthesia, tremor and ataxia. In some studies improved bladder control was observed. There is also some anecdotal evidence of a benefit of cannabis in spasticity due to lesions.

In a number of painful syndromes secondary to inflammatory processes (e.g. ulcerative colitis, arthritis), cannabis products may act not only as analgesics but also demonstrate anti-inflammatory potential. For example, some patients employing cannabis report a decrease in their need for steroidal and nonsteroidal anti-inflammatory drugs. Moreover, there are some reports of positive effects of cannabis self-medication in allergic conditions. It is as yet unclear whether cannabis products may have relevant effects on causative processes of autoimmune diseases.of the brain.

NABILONE

NAUSEA

Treatment of side effects associated with antineoplastic therapy is the indication for cannabinoids which has been most documented, with about 40 studies (THC, nabilone, other THC analogues, cannabis). Most trials were conducted in the 1980s. THC has to be dosed relatively highly, so that resultant side effects may occur comparatively frequently. THC was inferior to high-dose metoclopramide in one study. There are no comparisons of THC to the modern serotonin antagonists. Some recent investigations have shown that THC in low doses improves the efficacy of other antiemetic drugs if given together. There is evidence from clinical studies that cannabinoids also effective in nausea and vomiting due to radiotherapy and after surgery. In folk medicine cannabinoids are popular and are often used in other causes of nausea including AIDS, hepatitis and nausea in pregnancy.

PAIN

Several surveys showed that relief from chronic pain is the most common condition mentioned by patients who use medical cannabis. A large number of clinical studies have shown the analgesic properties of cannabis products. Among possible indications are neuropathic pain due to multiple sclerosis, damage of the brachial plexus and HIV infection, pain in rheumatoid arthritis, cancer pain, headache, menstrual pain, chronic bowel inflammation and neuralgias. The combination with opioids is possible, and some studies indicate moreover that the use of cannabinoid medicines may lead to a reduction in opioids consumption.

PRURITUS

According to small clinical studies cannabinoids taken internally or externally as ointment ameliorate pruritus by different causes, for example, severe pruritus in the course of liver diseases.

SLEEPING DISORDER

According to a few studies and case reports, cannabis or cannabinoid medicines may alleviate sleeping disturbance, specifically among patients with obstructive sleep apnea, fibromyalgia, chronic pain, or multiple sclerosis.

SCHIZOPHRENIA / MENTAL DISORDERS

An improvement of mood in reactive depression has been observed in several clinical studies with THC. There are additional case reports claiming the benefit of cannabinoids in other psychiatric symptoms and diseases, such as sleep disorders, bipolar disorders, schizophrenic psychosis, and dysthymia. According to some case reports THC was effective in otherwise treatment-refractory heavy compulsive disorders. In addition, studies and case reports also suggest that cannabinoids may be beneficial for improvement of anxiety symptoms. Cannabinoids may also reduce symptoms of posttraumatic stress disorders, such as nightmares, global clinical state, and general well-being. Various authors have expressed different viewpoints concerning psychiatric syndromes and cannabis. While some emphasize the problems caused by cannabis, others promote the therapeutic possibilities. Quite possibly cannabis products may be either beneficial or harmful, depending on the particular case.

TOURETTE’S SYNDROME

There are some positive anecdotal reports of therapeutic response to cannabis in Tourette’s syndrome, dystonia and tardive dyskinesia. The use in Tourette’s syndrome is currently being investigated in clinical studies. Many patients achieve a modest improvement, however some show a considerable response or even complete symptom control. In some MS patients, benefits on ataxia and reduction of tremor have been observed following the administration of THC. Additionally, cannabis products may prove useful in levodopa-induced dyskinesia in Parkinson disease without worsening the primary symptoms.

A small study showed that inhaled cannabis improved the motor symptoms of patients with Parkinson’s disease, including tremor, rigidity and bradykinesia. Despite limited evidence regarding effectiveness for treating patients with Huntington disease, the American Academy of Neurology guideline concluded that “nabilone (a synthetic derivative of THC) possibly modestly improves Huntington’s disease chorea.” Anecdotal reports of patients with Amyotrophic Lateral Sclerosis (ALS) suggest that cannabis may provide symptomatic benefits to such patients. Similarly, patients’ reports point to the potential of cannabis in alleviating symptoms associated with Dystonia.

MISCELLANEOUS, MIXED SYNDROMES

There are a number of positive patient reports on medical conditions that cannot be easily assigned to the above categories, such as hiccup, high blood pressure, tinnitus, chronic fatigue syndrome, restless leg syndrome, and others. Several hundred possible indications for cannabis and THC have been described by different authors. One example is the successful treatment of a chronic hiccup that developed after a surgery. No medication was effective, but smoking of a cannabis cigarette completely abolished the symptoms.

Cannabis products often show very good effects in diseases with multiple symptoms that encompassed within the spectrum of THC effects, for example, in painful conditions that have an inflammatory origin (e.g., arthritis), or are accompanied by increased muscle tone (e.g., menstrual cramps, spinal cord injury), or in diseases with nausea and anorexia accompanied by pain, anxiety and depression, respectively (e.g. AIDS, cancer, hepatitis C). This is also the case for elderly patients, who often suffer from multiple symptoms and comorbidities.
