My new housemate/friend was recently kicked out of the dorms, and as a friend I allowed him to move in. He's been living with me for the past 6 weeks, and in this time I haven't experienced any aggressive or negative behavior. However, he's withdrawn from all classes for the spring semester and has no job. Instead, he scours the neighborhood streets for junk to sell. He’s a smoker, has tried numerous meds for ADD (currently on a high dosage of vivance), and has admitted to using drugs (namely marijuana, shrooms, and ecstasy). Also, he hasn't managed to finish his BA in spite of being enrolled for 7 yrs.
I’ve been suspicious of drug use because of unusual sleeping episodes. For instance, I’ve seen him sleep for durations longer than 12hrs, and he’ll wear sunglasses indoors afterward.
Yesterday, revealed a lot more to this puzzle. I had to wake him up after an 18hr period of sleep because we had plans to hang out with a friend. He wore sunglasses the whole time, didn’t seem “present” (at one point, he noticed he had put his shorts on backwards); and while he was checking out at the store, our friend and I noticed him sort of teetering. Once we got back, our friend and I decided to play videogames, but my roommate said he’d join us later. He never came back. A little after midnight, as I was requesting an Uber to get our friend home, I walked past my roommate’s bedroom - door ajar - and saw him on the floor lying on his rolled-up foam mattress. His face was flushed red, and he appeared to be knocked out. I called my friend over to take a look. We both felt strongly that he was on something, but neither of us do drugs, so we weren’t sure.
Later that evening, my friend called me with much concern in his voice. He urged me to lock my bedroom door, keep a knife and my cell within grasp.
Like I said, he’s been living with me for about 6 weeks now - no belligerence or contrary confrontations with him at all - and he’s paid his share of the rent. However, I was a little shocked and concerned after learning of his interest in the occult. That was a major red flag to me, but because I’m moving at the end of school (1.5 months from now), I feel like I can just tolerate him.
Any thoughts or advice on this situation?
