Hey, I would like to know the long term effects of mixing tobacco and marijuana on the body. I m an 18 year old male, in pretty decent shape I work out frequently but unfortunately I have been mixing tobacco and marijuana and smoking it out of a bong for a year and a half now, almost on a daily basis and I m starting to notice some issues, I smoke only 2-4 grams of marijuana a week but I only smoke with tobacco. Anyway, I m noticing recently that I sometimes get chest pain and irritation and I m also experiencing muscle tension in my neck after I smoke which is very, very recent. I am aware this isn t healthy and I have been cutting back, I plan on cutting tobacco out of my life completely. I would just like to the long term effects of inhaling these two substances dailyknow if I should go to a doctor to get my lungs checked out
