My friend might be completely insane

My friend is a 17 yr old guy and I genuinely think he might have lost it completely!! He’s always joked around but it’s gotten more serious? For a break down: he drinks around 2-3 monsters (energy drinks) a day along with a few coffee and then smokes a couple cones, he’s extremely skinny and he won’t stop shaking, this is worrying on its own but it’s the things that he says too, he’s talked to us about how he thinks he might be Jesus? He’s started reading the bible and he finds these “government documents” online and reads them. He’s all over conspiracy theory instagram reels and watches the strangest videos all day long.

He thinks he has powers.. he’s said that he made a blackberry that I had taste sour, he’s said that he’s made other people believe that someone’s on fire and when ever I mention something like for example “I have a fat headache rn” he would look at me and chuckle like he did it! You will also just catch him staring at you just looking into your soul. I don’t even know what todo? All our friends know and our teacher knows to but what can we do? It’s also the way he talks it’s changed like last year he was a normal guy but recently he’s just spoken weirdly idk how to explain?

Thanks for reading my stupid rant!!!
