material safety

I love how the acrylic looks on the Tetra P80 but am wondering if there are any heath concerns there with touching it in general (or touching it than rubbing my eyes) or having in near the air or vapor path in anyway? Honestly just paranoid about that sort of thing lol and was wonder if anyone...

I have a vape, but currently don't own a glass piece. I should be getting one soon...but for now I'm using a beer can and an aluminum one-hitter as a bong. I know that's pretty crappy...Anyway, is there risk from using an aluminum beer can with a vape?
