Kent D Range Quality Drop - Throat Pain, Phlegm, Migraines After Smoking

I've been smoking Kent D Range for a long time, but lately, the product has visibly changed in some way. The quality of the cigarettes has gone down a lot. They make my throat hurt, give me a lot of phlegm, and even give me migraines after I smoke. I remember how this cigarette used to taste and feel, but now it's not the same at all. I buy one of the most expensive brands on the market, and anytime the price goes up, it goes into effect right away. But the quality keeps becoming worse. I'm really upset about this and want you to go back to the prior level of quality in production. If this problem isn't fixed, I'll file a complaint on every site that matters.
