We can look at intent: comic publishers want to make them interesting and capture your attention for some time, but do they make them addictive? And we can also look at the scale – if a product is reliably addictive across a wide audience, it might be bad for society, not just for individuals. If both criteria are met, it’s probably reasonable to blame the “dealer” of the thing in question.

But I agree that we should be able to decide for ourselves what is good for us – delegating it to authority isn’t a great solution, it should always be our own responsibility. We should, however, be especially cautious when making decisions about things that are known to be addictive for others.
