Is the punishment and prohibition of smoking equal to the punishment and prohibition of looking at pornography, and what is the relevant religious text that indicates this?

One of the most important sciences is the jurisprudence of the hierarchy of deeds, to prioritize what is most important when there is a conflict. It appears that watching pornography is more forbidden than smoking, as it is closer to being a major sin due to what it leads to in terms of falling into indecencies, and due to the approval and contentment it implies with major sins, in addition to the effect of unlawful gazing in corrupting the heart and distancing it from good. It is incumbent upon the Muslim to guard against all sins and to hasten to repentance.
