Hello and welcome to Healthcare Magic. Thanks for your query.
It is possible that you could have aspirated some of the ash / debris of the burnt material. Since you have developed symptoms like chest pain
after this incident, it is better to get yourself checked by a doctor.
So, I would advise you to see a doctor for a physical examination, and if necessary, a chest X-ray. Also, in the future please refrain from such harmful practices. Smoking
marijuana itself can also cause a variety of adverse health consequences. So, please consider quitting and don't hesitate to seek help for this, if you need to.
Wish you all the best.
Dr. Jonas Sundarakumar
