I eat sponges and smoke. My stomach burns after eating real food, is it from the sponges or cigarettes?

I buy a pack of 3 per week so the sponges are clean and safe from bacteria and I smoke about 6 cigarettes per day. Recently, like for about a month my stomach started hurting and burning after eating and I can only really eat one meal per day. Is it from the sponges or cigarettes?
