Hello Recently I've Been Smoking From A Wax Pen. I

Hello recently I've been smoking from a wax pen. I don't really use it often but lately I've been coughing for the past 5 months like I have mucus in my lungs. I assume it's the wax I've been smoking that is why I stopped. What would you reccomend I do to take out the excess wax that has stayed in my lungs? Are there any medicines that can help me recover? Thank you.
