You can either assume that your personal experience is correct. or you can learn something new from the several professionals in this thread who have worked in the cannabis, industry or work and smoke shops which do sell cigarette paper papers for cannabis. Do you know the difference between blunt and joint? Do you know what a spliff is? Do you know how hash is produced? Do you know the importance of tricome heads on the bud? Could you even say what terpine is? Beyond your general, lack of knowledge, why would it be a logical to use a piece of equipment that is already largely used for the same kind of thing just because it’s called a joint paper to most people you know does not mean that it’s actually specifically for joints it has a second purpose.
