Can I pray in clothes that smell of cigarette smoke?

Yes. A smell alone does not make clothes impure, and cigarette smoke is not najis. You can pray in clothes that smell of smoke, though it is considerate to freshen up, especially before you join others in a mosque.
Najis is a substance, not a smell
Najis means a physical impurity, such as urine, blood or feces, that must be washed off your body, clothes or prayer place. Smoke is not on that list, and neither is ash. Many ordinary smells are the same: cooking, incense, perfume, sweat, or a pub or party you walked through. A strong smell may annoy people, but it does not affect whether your clothes are valid for prayer. If you want to check a real stain, see Can I pray with a stain on my clothes?
Smell and the people around you
Islam does care about smells in the place of prayer, because worshippers stand shoulder to shoulder. The Prophet ﷺ said that whoever eats garlic or onion should keep away from our mosque (Sahih al-Bukhari 855). In another report he explained that the angels are harmed by the same things as people (Sahih Muslim 564). Scholars apply this by analogy to other strong smells, including heavy tobacco smoke.
So the prayer itself is valid, but if you are heading to Jumu'ah or a group prayer, a little effort is a kind thing to do for those next to you.
Simple ways to freshen up
- Hang your coat or top outside or by an open window for a while.
- Swap into a clean shirt or jumper before you leave.
- Rinse your mouth well when you make wudu, and brush your teeth.
- Wash your hands and face, since smoke clings to skin and hair.
- Keep a spare scarf or top in your bag if you work around smoke.
If you smoke yourself
Many scholars today consider smoking harmful and therefore forbidden, while others call it strongly disliked. Either way, being a smoker does not stop your prayer from being valid, and you should never skip a prayer because you smell of smoke. Pray first, then keep working on quitting. Many new Muslims find it a gradual process, and it helps to ask for support. See Do I have to quit smoking before I become Muslim?
If you are going to a mosque, see What should I bring when I go to the mosque? for small things that make it more comfortable for you and for others.
- Only a physical impurity makes clothes unfit for prayer, not a smell.
- Smoke and ash are not najis.
- Be considerate of the smell when you join others in the mosque.
- Do not skip prayer because of smoke or because you smoke.
