Cigarette/Marijuana Smoke Detection Options

[Denis Ponder]

Good morning,

Does anyone have any suggestions on devices or detectors we can add to the inside of our property to detect marijuana or cigarette smoke?

Long story short, we had a recent guest smoke marijuana in our place which was a blast to clean and get ready for the next guests.  We got them on camera outside AND they were smart enough to leave some bud on our table inside for additional evidence.  Big thanks to @michael baum for answering some questions over the weekend via DM!  This community is great.

Thanks for any recommendations you can provide.
