can cause respiratory problems because of the chemicals you are inhaling, possibly. With all the substances you are binging on, you are putting a huge strain on all types organs and parts including the lungs. Some people do have breathing problems after smoking methamphetamine
and some of those people have underlying problems such as asthma ect...
I would say to slow down or halt the binging on multiple substances and get a routine check up while letting your doctor know about your breathing. Make sure there is not a problem and remember, the body is not an immortal vessel you can put all kind of different things into without problems, sometimes big and sometimes small. Mixing substances such as MDMA
and methamphetamine is terrible for the heart and other organs, please make sure you are okay before continuing the harsh partying.
