Oh for sure it could be any number of things i agree. But highly unlikely is meth.

Possibly emphatamines or coccaine but actual meth use is almost unheard of in Baltimore. Im sure it exists in single cases or from out of towners but is really rare.

Are you an officer? No I don't get down there alot but I've been a first responder in Baltimore for 17 years and never once had a patient with meth or walked into a meth lab environment that we are trained on. If im wrong I'm wrong but I've never seen it

The fire department uses a 5 gas meter that is very expensive so the VOC detector is a moot point if they brought out their 5 gas meters. Some chemicals like chlorine though are not part of those 5 gasses. It is HIGHLY unlikely they are cooking Meth. Extremely rare in Baltimore and surrounding areas.

Meth doesn't get made in Baltimore. I can promise you that it is EXTREMELY rare. It just doesn't sell here or in the surrounding areas.
