URGENT suggestions needed on tenant screening

[Piku Nanda]

Hi All,

I have been a landlord for 2 years now. I use Transunion smartmove to screen my tenants.

I am currently reviewing an application of a tenant who has 1 criminal record . This person was found in possession on 1 ounce of marijuana 6 years ago. They were put on probation at that time . When the potential tenant first met me , they were upfront and mentioned that they were arrested for marijuana 10 yrs ago (which I now found out was 6 yrs ago , but still far enough in the past) . Other than this, the rest of the results are decent (no negatives on credit even though they have only 4 credit accounts , no evictions). 

Also, when I met this person, they seemed to be a high energy individual (I am quite laid back so cant really tell if this was just a regular happy person or a person high on drugs).

I am a pretty boring kind of person and have never had anything to do with marijuana. I am in a dilemma whether on not to rent to this person. If I rent to them and they end up using marijuana, what sort of damage can they do to my property ? How big of a deal is a one time marijuana related arrest ? Is there anything I can do to minimize my risk and still rent to them?

Please share your thoughts.

Thanks
