Let's use an analogy:

What if someone was burning a tyre in my neighbour's garden directly affecting my health?

You can't up the ante and claim it's analogous. Burning a tyre releases a tremendous amount of thick black smoke, burning a joint releases several orders of magnitude less smoke, and unless you're within 10m of the person you realistically are not going to be affected.

For effect: "What if someone built a rocket launch pad next to my house and it was directly affecting my health?"

Doesn't that depend on how far my neighbour is away? Perhaps we have 500m long gardens...

The analogy is valid as is "pissing over my fence onto my head", "kicking a football through my greenhouse", "catapulting dog shit into my garden" etc etc.
