nino those are def oxies but if hes sniffing a lot of them now he will surelly get to dope because its much cheaper. the second one of this friends convinces him to try the needle because its so much better its over. for meth look for a pipe with a dome at the end prob clear see through glass or needles. crack look for a straight glass stem one you find on those cheap roses and look for brillo filter and charr on the end
