Calling to cops to prove my tenant is smoking weed?

[Devin M.]

My neighboring tenants smoke so much weed that the smell fills my half of the duplex. I was going to give them the notice to cease as a warning, with the promise that if smelt again, we'll move forward with the eviction process.

Since I have to prove it, after I give them a notice to cease, should I call the cops to verify that my claims are valid so there's some legal "validity" to my claims in court if the eviction process goes further than the notice to cease?

Sorry for posting this in the off topic forum section as well. Couldn't figure out how to "move" the post and duplicated it here. Thanks guys!
