Glad to have found this thread. I recently asked about "ouddiction" on the general board but got very little feedback. I wonder if this topic might be a bit taboo among some on this forum.
Addiction might be the wrong word, as it denotes overall personal disfunction, and also is often associated with physically debilitating withdrawal symptoms. Even if we're focused on the compulsive buying and collecting of oud rather than on physical addiction to oud as a substance, I doubt that this compulsion is likely to reach crisis-level, large-scale breakdown of a person's life. Or if it did, then as Anmar said, oud is not the culprit but the object of a neurosis. A person could compulsively collect rare books or spend uncontrollably on jewelry, but in in neither of those cases would we label the substance as inherently addictive.
However, being that oud is positively psychoactive, the substance can influence our behavior. No, it will never cause a physical dependence to the extent of heroin, alcohol, or tobacco, but what interests me is that oud might become something our brains begin to associate with day-to-day life. If a person finds that Oud helps them sleep and then begins to use it every night, they may find that they need more and more of it to fall asleep, or they might try to to stop self-medicating with oud, only to find that its harder to sleep at night than it ever was before oud (a sort of oud withdrawal).
Or, if a person finds that oud enhances their spiritual practice, be it yoga or meditation or prayer, they might begin to rely upon it for a deeper experience, but if they no longer have oud, they may struggle to make it through their routine, and this struggle might be greater than it ever had been before their brain came to expect the addition of oud's powerful aromatic molecules.
The point here is to be wary of relying regularly on a substance, because the brain will adapt. Before you know it, you could find that, instead of an elevation above your baseline state, oud helps you feel normal, and the lack of oud is the exception that needs remedying. I don't suppose this means that swiping every day is always bad, but means to be careful that regular oud use is voluntary and not routine, a free and pleasurable enhancement rather than a habitual and necessary addition that solves a problem.
Safe swiping, friends!
