Black boogers??

So I noticed the other day some black stuff on my mask and I noticed some was in my nose. I had originally assumed the mask was dirty and something got into my nostrils but I later blew my nose and black boogers came out. I did some research and it all came down to pollutants and toxic things being cleared from your system through mucus. The thing is I've been smoking for over 3 years and this has never happened before. I've recently upped the frequency with which I use (mainly because I was trying to learn how to ghost 😂) and right after that the black mucus started showing up. I'm just looking for a second opinion but do you guys think this is cumulative is a result from smoking frequently for the last few years or if it's because I was just using more than usual recently? Should I stop all together? Also I'm not a legal adult and I have a pretty strict family so I can't really ask for help unless I think its something immediately detrimental to my health.
