that's not a very accurate way of phrasing it. in some scales it's considered similar in abuse potential but that is extremely different than physical harm.
both are considered medium for abuse potential. cannabis is so non-toxic it doesn't even chart for physical harm. mdma is medium toxic, especially with sustained use.
