<human>: He is my cousin, he is 15 years old, and we both live with our grandparents. I live there because it is closer to my work and he lives there because "it is closer to his school." I love my cousin to death as a family member, however, he never listens to anybody and doesn't contribute toward cleaning the house. He basically just comes to eat and sleep and smoke weed in his room. It is practically a free all-inclusive hotel for him. At first I didn't really mind... however it is getting a lot worse, he mistreats my grandparents, which pisses me off due to the fact that they are more fragil and they cant really take that kind of stress due to the fact that they have health complications, and the amount of weed has increased over time. He now smokes inside the house which really gets everyone mad because the smell penetrates our clothes.

 So to get to my point... I was wondering if there was a way to maybe scare him into shaping up, maybe calling the police anonymously? Im in California so I am pretty positive that marijuana only gets you a slap in the wrist.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Brat smokes weed and takes advantage of grandparents hospitality. Want to make an anonymous report because the amount of weed has increased by a lot.
