Any drug expert?

So, the couple living next door have made the entire building smell super weird and I'm almost positive it's some kind of drug since the girl told me they smoke. Can drugs cause headaches? Cause my head's been hurting since this morning. Normally I'd assume it's from excess of gaming, but this one feels really weird and unlike the others I've had so far.

While it's not drugs, our office is next to the molding shop at my work. Sometimes they burn the plastic on accident and the place smells terrible all afternoon. Head aches usually ensue. If you really wanna test out if it's the air around the place that's bothering you, go out somewhere else for some fresh air and see if your head clears up. Whenever I go home for lunch on those burn days you can feel the difference almost instantly.

Super weird? Like musty? That'd just be an old ill kept place. Chemicals and smoking? Meth, maybe? No one knows until it's checked out, we can make all the assumptions we want. Sometimes there's this thing where we fool ourselves into thinking it's something else causing an ailment when we are just sick, but if you continue to believe it's something else , the headache could just keep happening...kind of like a placebo effect. Talk to your leasing office and let them know your concerns.

Talk with the landlord saying you're smelling something next door and it's giving you a headache. No need to make assumptions when they could just be sacrificing a goat.

I wonder what meth smells like? I actually have no idea. I could identify coke instantly but know nothing about meth. Wonder if they might be cooking it? It can put off nasty fumes from what I've heard.
