Liquid and spray aren't the only types of contact adhesive. There is also powder and foam adhesive and some people prefer these as well.
I'm not a fan of spray adhesives because they are messy and I feel that they are more harmful because the toxic gases spread all around. It's best to use these outdoors and not indoors. Even when using liquid adhesives, it's necessary to open a window. Non-toxic adhesives are nice but unfortunately, they don't hold as well.
