We recently closed on a new 5 unit property in Concord NH. During the home inspection, one of the units had marijuana spread all over the coffee table. Not sure if we're talking illegal amounts, but it was strewn about and a mess (on the table and the carpet). Sure enough at the final walk thru it was a similar scene. Both times I didnt have a chance to meet the tenant. Now that we have closed, we're contacting the tenants to fill our info forms (found on BP!) and will start making leases for the new tenants. What do the new marijuana laws allow? 

1.) If its just for recreational use can we ban it from the property. We have a section on illegal drugs, yet, marijuana is a grey area. We do not want smoking of any type. I wouldnt care if they were making brownies or something like that... certainly not trying to hide it though.

2.) What if they have a medical card? I am sure I can still ban smoking right? I have a buddy with a medical card and he buys cookies and brownies and other non-smoking types.

What other matters on the topic am I forgetting? If all else fails, hes a tenant at will and I can just evict him if Im not happy.
