Your neighbour is scary: that sort of thing could eventually kill you! As a sufferer from anaphylaxis (basically life-threatening allergies), I carry around an Epipen. It's not a cure, but it does allow the symptoms to disappear for 10-20 minutes (just enough time to get admitted to a hospital).

I guess you didn't see that one coming Sorry

Do you not have green bins in the US?

you should have caked 911 and made it seem worse, gone to the hospital. It was inflicted by the neighbor so the police would have been brought in. he would have been charged with assault and public endangerment.

I'd tell you to sue him but I doubt that you'd see half of it.

OP's case aside his neighbor should know better than to burn that stuff. Illegal or not, sounds like OP's neighbor is one that needs all those warning labels like "caution hot" on a oven etc. CDC states to not burn the plants though common sense has told me not to, to begin with. FYL

Perhaps you can get him to plant a less offensive weed in its place?

Have you tried seeing the situation from his perspective? Oh.. Sorry...

Doubt he thought you were allergic but maybe tell him for the next time :)

Habanero oil on the doorknobs. And poison ivy (if you can do it without aggravating your allergy) on the toilet seat
