Numerous global studies often use national epidemiological surveys to investigate comorbidities related to the use of psychoactive substances, including cannabis. Although national epidemiological studies are useful for cross-country comparisons, their goal is not to create a comprehensive tool for researching the psychosocial aspects of cannabis abuse. Therefore, they overlook some etiological and phenomenological aspects of cannabis consumption. Given that cannabis is the most widespread illegal psychoactive substance and that most users consume it occasionally, sporadically, but over a long period, it is important to approach this issue from multiple perspectives. This study aims to assess the manner, form, quantity, and frequency of cannabis consumption in relation to gender and age, using the instrument Daily Sessions, Frequency, Age of Onset, and Quantity of Cannabis Use Inventory (DAFQ-CU), by Cuttler and Spradin (2017), with the intention of gaining a more detailed understanding of occasional but long-term consumption. The sample is convenient, consisting of adult cannabis users in Croatia who anonymously and voluntarily complete an online questionnaire. The data will be analyzed using descriptive statistics, comparative analysis, and correlation analysis. The results will be discussed with the aim of contributing to the development of online support programs for reducing and ceasing cannabis use among adults.
