I don't see a way to force someone to leave more effective than direct confrontation with the person.
There are, of course, things like hot foot powder. But within the same home, that brings risk to the others who also live there.
If the place is rented, then a plea with property management may be in order: The person is destroying rented property, and you do not want him to lose everyone's chance of getting the deposit back, or however you can word it with the property management. If the place is owned, then hopefully the person has signed a lease or rental agreement of some sort. That can be taken to a judge with photographs, for an eviction order.
I will say this about the possible state of mind of the person: It seems he might be at least somewhat using the substance as a coping mechanism for his emotional state, which he is not willing to address more directly. In such cases, it can compound issues. It's an aspect of my own practice, and why I definitely suggest professional help: Coping in a way wrong for a person can lead to a worse condition. And just meds won't always help. The person must learn to deal with their own inner world in order to get any sort of better.
