Warning new tenants about the weed...?

[Nancy DeSocio]

Hello BP community!

I'm about to advertise a 3rd floor apartment and could use some advice on how to handle this situation.  The 2nd floor tenant has a medical marijuana card and smokes outside.  She's also on a lease, so asking her to leave is not an option at this time.  The smoke rises and wafts into this vacant unit (one of the reasons the last tenant left).  Would you say anything to prospective tenants when showing the unit?  It's no one's business why the 2nd floor tenant smokes, but it seems wrong to withhold this information if it's going to bother the new tenant/family upstairs.
