@Nanxing0 Something that a reader of a blog quotes from one customer-service operator is not what I would call a "clear policy." It would be correct to say that illegal drugs are not permitted, but only because, by default, local laws always take precedence over Airbnb policies.
Still, the majority of addictive and behavior-altering substances that people consume (e.g. alcohol, prescription drugs) are not illegal. Hosts are entitled to their own rules about what people can consume on their property - of course you know this as a host with a no-smoking policy - but the statement you quoted does not touch upon guests being under the influence of something they consumed outside of the property.
My advice to any host who suspects their guest to be a problematic drug user is to focus specifically on the behavior, and not on their suspicions about the cause of their behavior. If a guest is acting in a way that endangers the household or makes you feel unsafe, it doesn't particularly matter whether it's a legal substance, illegal substance, or mood disorder that caused them to act that way; the actual behavior is the thing you have to deal with.
@Charlotte-and-Sturle0 I can't gather from your description what it is about this guest that caused you to feel that she is any more of a danger to your family than any other stranger from the internet that you might have allowed to stay in your home for a month. Even if all of your guests are attractive and affluent, there are a lot of risks involved in this. If there's been an incident that gives you cause for concern, your first step is going to be communicating this to your guest, and making sure there is correspondence in the Airbnb messenger giving you a record of that dialogue. If you're unable to reach a resolution that leaves you feeling safe, you can terminate the booking. Airbnb can not force you to host against your will; they may penalize you if you can't provide a satisfactory reason, but as a parent I'm sure you prioritize your children's well being over your Airbnb listing.
Try to think of it the other way around: if you had a guest that was uncomfortable with you or your household, what would you want them to do? Call Airbnb behind your back and accuse you of being a drug addict, or communicate their concerns to you like an adult?
Your guest may be unattractive, unkempt, and inattentive, but these qualities won't rub off onto your kids. What will rub off onto them is the way you treat the people who come into your household, and the attitude you take to those who don't appear to fit in to your "upper class neighborhood." Calling them "super sketchy" because you don't like the look of them might not be the ideal message there.
