Illinois Medical Marijuana Products and Dosage Methods
There are multiple dosage methods for cannabis usage: inhalation, ingestion and topical applications. Each method produces a unique medicinal effect, even if the patient uses the same strain in different ways.
Takes Effect in 1-5 Minutes
Effects Last 1-4 Hours
Many patients choose to inhale cannabis via a rolled joint, pipe or vaporizer because these dosage method are convenient and fast acting. However, respiratory tract irritation is a short-term side effect. Current research finds that the long-term side effects of smoking cannabis are minor, however habitual and heavy smoking of cannabis may cause phlegm production, bronchitis and chronic coughing. Cannabis smoke is known to have substances that cause cancer, called carcinogens. When studied at a molecular and cellular level, the cannabinoids in marijuana are shown to lower the effect of the smoke’s carcinogens and no verified cases of lung cancer or other lung diseases have been found in cannabis smokers.
Kief and hashish, or hash, are two popular popular cannabis products. Kief is a powdered substance made from the resin glands of marijuana plants. Kief is compressed to create hash. Hash has a paste-like texture and a THC content that rages from 15 to 70 percent. Kief and hash may be inhaled or ingested.
Extracted from mature cannabis foliage, hash oil is a combination of the resin and other essential oils. Hash oil ranges in THC content from 30 to 90 percent. This oil can be added to food or smoked in a joint, pipe or specialty hash pipe.
Takes Effect in 1-2 Hours
Effects Last 6-8 Hours
Cannabinoids reach maximum potency when heated, and they are fat-soluble. Therefore, cannabis may be added to many drinks and foods. Heat is necessary to create active THC and CBD. Since ingested cannabis is processed by the body’s liver, patients may experience stronger and longer-lasting psychoactive effects, especially when using products high in THC. The most common ways to ingest cannabis are through:
– Cannabis butter, which is cannabinoid-infused butter;
– Cannabis oil, which is made in a similar manner to cannabis butter, but it is a blend of cooking oil and cannabinoid resins;
– Cannabis liquor, which is an infusion of leaves and stems with rum, brandy or other alcoholic beverages;
– Cannabis beverages, which includes coffee and tea. Since the cannabis resins are not soluble in water, some form of oil must be added to coffee or tea to ensure that the resins dissolve in the beverage.
Another ingestion method is via a cannabis tincture. As concentrated cannabis liquids, cannabis tinctures take effect in 5-30 minutes with effects lasting 1-6 hours. The fastest way to introduce a cannabis tincture to the body is by holding a few drops under the tongue for one minute before swallowing the liquid. This product has a low odor, and it is easy to dose. Tinctures also come in sublingual sprays.
Medicinal cannabis is also available in pills and sprays, with effects that are very similar to those resulting from the preparations above.
Several prescription cannabis-based medications are available in pharmacies. Dronabinol, a Schedule III drug, is a capsule that contains synthetic THC in sesame oil and can be prescribed by physicians. These pills do not contain any of the other cannabinoids, and they are designed to treat weight loss and lack of appetite in AIDS patients as well as vomiting and nausea in chemotherapy patients. Sativex is a mouth spray that is used to treat aggravating symptoms in cancer and MS patients, such as overactive bladder, spasticity and neuropathic pain. Sativex is not yet available in the United States.

The plant and its oil extracts can be added to lotions, salves and balms to make topical products. Topical cannabis does not create psychoactive effects in patients. These products are effective at reducing pain and inflammation. Topical cannabis can treat numerous ailments, such as:
– Allergic Skin Reactions;
– Muscle Strains;
– Post-Herpetic Neuralgia;
Although cannabis has an extraordinary record of safe and effective use spanning many centuries, it is important to use as little as is needed to achieve the medical benefits for which it was recommended by your doctor. Less may well be more when using medical cannabis. Bear in mind that cannabis has a biphasic dose-response curve, which means that symptoms that are improved by using cannabis at low doses may be exacerbated, or made worse, when it is used in high doses. Nausea is a good example of this. At low doses, marijuana can prevent nausea, while in high doses, it can create nausea or make it worse.
Negative Side Effects
As reported by anecdotal evidence and scientific research, cannabis in all its forms is a very safe treatment. Usually, any negative side effects are easily tolerated and mild. Anxiety attacks, convulsions and temporary psychosis are very rare complications, typically caused by ingesting too much edible cannabis or smoking cannabis high in THC, and are more likely to occur in patients who have never used medical marijuana or novice or use it infrequently.. It is impossible to fatally overdose on cannabis. Over time with regular use and dosage adjustments, many of the psychoactive effects are decreased. The possible negative side effects of cannabis usage include:
– Decreased sperm count (seen only in animal experiments and not yet in humans, but worthy of noting)
– Eye redness;
– Impaired psychomotor performance;
– Short attention apan;
– Short-term temporary memory loss;
– Decreased REM sleep patterns
Long-term, heavy cannabis use may impact reproductive hormones, possibly causing decreased sperm counts, however, it does not cause infertility. There is evidence in animals that fetal exposure to cannabis may carry a higher risk of cognitive deficiencies, small birth weight and premature delivery, but there is no research evidence of similar effects in humans. Nonetheless, it is important for women who are pregnanct or may become pregnant to avoid using cannabis until scientific research can definitively determine whether its use in pregnancy also has negative effects in humans.
While cannabis is shown to improve mental conditions, such as ADHD, PTSD, bipolar disorders, depression and anxiety, some patients may find that cannabis aggravates the symptoms of their disorder. Therefore, patients who have been diagnosed with a mental illness are encouraged to consult with their doctors before using medical cannabis, and regularly while using it
Although there is conflicting research on whether cannabis use in hepatitis C is beneficial or detrimental, patients diagnosed with hepatitis C should be judicious in their use of cannabis
Patients who smoke cannabis from a water pipe on a regular basis should change the water often to reduce the accumulation of bacteria and viruses.
Cannabis patients should refrain from driving for a minimum of two hours after using marijuana by inhalation, and should carefully assess their ability to drive or carry out complex tasks after using tinctures or especially ingested cannabis products. Keep in mind that cannabis can cause impairment of motor skills that may last for several hours, and that driving under the influence of cannabis, especially THC, is considered a crime in most states.
There are no major interactions between any drugs and cannabis. However, cannabis may intensify the effects from opiate and hypnotic medications. Initial studies have found cannabis to interact with medications such as antihistamines, barbiturates, disulfiram, fluoxetine and theophylline, and may alter the metablolism of antiepileptic medications. Caution should be used when mixing cannabis and alcohol due to the combination’s ability to amplify the effects of both substances, known as a synergistic effect. Research in France has shown that the degree of impairment resulting from the combination is alcohol and cannabis is greater than either alone, and may last longer as well.
