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.
