@Nancy288 Did you know it was a third-party booking? If not, report it to Airbnb. Airbnb does not allow third-party bookings https://www.airbnb.com/help/article/427/can-i-book-on-behalf-of-a-friend-or-family-member
Call Airbnb to report that guest is breaking House Rules. If you can prove it, then you have two options: 1) tolerate guest unitl the month ends since the following month will not automatically renew; 2) have Airbnb cancel the reservation, which means you will not be paid for remaining days and your calendar will be blocked.
If you have proof of the smoking, send evidence to Airbnb via the resolution center as soon as possible. Document everything, send guest meassages using Airbnb messaging about the smoking, remind guest of House Rules.
