This study aimed to identify the level of irrational thoughts associated with addiction and drug abuse and their relationship to logical thinking among Jordanian university students. The study selected the target sample by using the simple random approach. The study was conducted during the first semester of the academic year (2021 / 2022) on a study sample of (866) participants. The study results found a high level of irrational thoughts related to (avoidance of problems, anxiety, and intolerance), and a medium level of irrational thoughts related to (lack of responsibility for emotions, and seeking support), in addition to a high level of logical thinking among Jordanian public university students. Also, the results revealed that there were statistically significant differences at the significance level (α≤0.05) in the level of (intolerance, anxiety, avoiding problems, and irrational thoughts as a whole) due to gender and in favor of males, and it was found that avoiding problems was in favor of females. Moreover, there were differences in the level of (intolerance, lack of responsibility, and irrational ideas as a whole) that are attributed to specialization and in favor of the scientific specialization. Furthermore, there were differences in the level of (intolerance, anxiety, support request, avoiding problems, lack of responsibility, and the total degree) due to the variable of the school year and in favor of the first year. Finally, there were differences in the level of (intolerance, anxiety, support requests, avoidance of problems, and the overall degree of irrational thoughts) attributed to the type of university and in favor of public university students. The study recommended the need to raise awareness among students in Jordanian universities and the need to participate in training courses that raise the level of logical thinking and increase their level of psychological toughness, self-improvement, and self-reliance.
