Is it normal for my hard palet to have whiteness? like closer to my teeth smal white lines i am a smoker and like spicy food

Maybe: Pehaps. You need an exam to rule out problems, See an oral surgeon. Especially in a smoker. Quit while you can to prevent future problems.

Smoker's Palate: Smoking plays a big part in several diseases and lesions in the mouth. See your dentist for evaluation and tests. Quitting smoking is not easy, but you can do it.

Evaluation needed: Have your dentist do an oral cancer screen. If the dentist feels that further treatment is warranted, you may be referred for evaluation of the area. At age 21 with your whole life ahead of you, quit now, it is not worth all the future health care concerns associated with smoking.

White lesions: Any white lesions of more than 2 weeks duration should be immediately investigated, especially if you are a smoker. Please immediately schedule with Family Dentist or Oral Surgeon for exploratory examination.
