Drug situation - How would you handle it?

[Morgan Nilsen]

Scenario:

PS. This took place in Norway, not in USA. Norwegian laws are not accepting weed as legal. Weed is also not socially accepted by most people.

Apartment is a 2 bedroom flat, where both bedrooms are rented out separately to students.

Both tenants are new. One a 22 year old woman, and a 18 year old gay man.

The 18 year old man was 17 when the contract started, and his mother co-signed as a guardian.

Both tenants are polite and up until now they seem to get on well.

1 month into their contract you get a complaint from the 22 year old that the 18 year old's room smell of weed. Also a joint-bud was left in her room while she was out of the house.

It is unclear if the man was granted access to the woman's room, but the contract prohibits smoking in the house, regardless.

How would you handle the situation? Would you contact the parents? Would you give a warning or terminate the contract that has a 3 month notice? Would you contact the police?
