smoking

If something affects your health negatively, logically it does affect your spiritual progress and well-being. Stop the addiction as fast as possible; any addiction that gathers roots in your mind and body must be dealt with as early as one recognizes this. Slight addiction in your case can be ceased instantly.

Most people around me smoke tobacco and I have a slight addiction

I don't know how true it is, but I read on a book that smoking closes your spiritual senses so much that mediums and spiritual people back then used to smoke a cigarette when some unwanted entity was disturbing them and/or they wanted to get their mind off the spiritual world.

Smoking also has an horrible impact on the pineal gland if I remember correctly.

So yes, it hinders your spiritual advancement.

Yes, smoking tobacco has a negative effect, but primarily harms your physical health.

Since smoking tobacco is a bad habit, you actually have a bad habit that can interfere with your spiritual development and that you need to get rid of in order to develop effectively.
