Neighbor's marijuana is somehow seeping into the house and making me nauseous
The neighbor smokes insane amount of marijuana. We live in a duplex. The smell/smoke travels from his house into my room. It's unbearable.
He needs to smoke. It's legal. Talking doesn't help. What can I do to "smoke-proof" my house/prevent it from travelling "through" drywall. I didn't even know it was possible.
