Can pornography harm you

it depends what you mean, well actually, it can't harm you at all, masturbation is considered healthy by most medical authorities, and the old wives taels such as "you'll go blind" are nonsense. ---- Yes, it can. Pornography leads to sex addiction, which releases the same chemicals in your as substance abuse. It is much harder to overcome because the drug is all in your head, you can just think about it and release the same chemicals while with substance abuse you need to physically have the drugs or alcohol. Those with sex addiction are usually in denial, and need to go through intense therapy to overcome it.
