Those who seek to reduce the unwanted effects of the Cannabis, such as the “high” feeling, anxiety, dryness of the mouth and others, can try using products with a higher content of CBD, since a high THC content is what causes most of the side effects. Another option is to reduce the dosages of the doses taken until readjustment and reduction of side effects, and in this case it is recommended to consult the treating physician before changing the dosage. In addition, the consumption of certain foods is reported to reduce the unwanted effects such as eating chocolate, sucking on a wedge of lemon, drinking citrus juice and eating certain salty foods.

As the use of medical Cannabis continues, so does the endurance against side effects develops and the side effects subside more and more with time. Of course there is no need to suffer during this period, and there are ways to relieve the side effects if they are presented.

Medical Cannabis is generally considered safe to use and its side effects are mild and are mostly tolerated by patients. However, it is important to know that in some cases there are more severe side effects, similar to other medications you choose to use. Side effects may include, dry mouth, Arrhythmia and changes in blood pressure, dizziness, changes in sugar levels in the blood, headaches or abdominal pain, trouble concentrating, thinking and in the perception of space and time.

Like other drugs, there are a variety of factors which determine the specific effect of the Cannabis on the users, which include among other things prior use of Cannabis, genetics, biological gender, form of administration and more. The composition of the active ingredients in the product being used, affects the effect felt. THC, for example, has a psychoactive effect, and the use of strains which contain a large amount of it will be accompanied also with the feeling of “high”, contrary to strains that are rich with CBD. Depending on the composition of the stain you choose to use, it is possible to generally assess the effect you can expect, however, as mentioned, there are many factors which affect your personal reaction to Cannabis, and therefore it is important to allow trial and error during the treatment with Cannabis in order to find the right strain and dosage for you, which will obtain the therapeutic effect with minimal side effects.

Second, one must learn the appropriate dosage, and finally, there is a need to familiarize oneself with the different strains and understand which one is more suitable to treat the patient’s condition. The many options of medical Cannabis treatments and the vast differences between the various patients, create a situation where there is no one treatment that suits everyone, and most patients go through the process of trial and error until they find the correct dosage, strain, and manner of consumption which suits them. The medical staff is able to assist with guidance according to the patient’s needs and wishes.

Strains with high levels of THC create a sense of “high”, whereas strains with high CBD levels are able to neutralize the sense of “high” caused by taking a high dosage of THC.

Cannabis is consumed primarily by smoking or vapor, as oil and rarely as food. The advantage of having a variety of administration forms, is that patients have the option to choose to consume Cannabis in the manner which most suits them and their therapeutic needs and in the most accurate way The main difference between the forms of administering the drug, is the amount of time each product requires to bring relief from the symptoms. Smoking takes effect in the shortest amount of time, and in a few minutes it is possible to feel the relieving effect of the Cannabis since the active ingredient reaches the blood stream quickly through the lungs. On the other hand, the effect of oils takes place after about 20 minutes or more from the time it is taken, since it takes time to absorb into the body. However, smoking Cannabis is expected to have a shorter effect relative to that of using the oils. In food products which contain Cannabis, the onset of the effect is even longer due to the need to absorb the substances through the digestive system, which makes it hard on patients to estimate in real time the amount of Cannabis they need to consume in order to obtain an effect, thus making this form of administration less common.

Some prefer to vapor the inflorescent of the Cannabis using vaporizers designed for that purpose. There are Cannabis extracts that are sold as oils that are dripped under the tongue or sprayed into the mouth cavity, and it can also be mixed in food products and be consumed.

According to the medical literature existing on the subject today, Cannabis can constitute a supportive treatment, leading to the improvement of many symptoms such as pain, insomnia, loss of appetite, anxiety and many more, however, at this stage, there is insufficient research evidence as to the ability of Cannabis to cure disease, and it is not officially recognized as medicine in Israel.
