Generally speaking, applying both Amphetamines and Cathinones, primary amine compounds are more peripheral and cause more intense side-effect, due to their strong norepinephrinergic effect. And you'll be able to understand from this fact, actually Amphetamine is about ten-fold acutely toxic than methanphetamine, based on LD50. If this might be the same in fluorine substituted analogues (not confirmed due to lack of articles) it seems to need more attention when using this as legal alternative to AMP/MAP.
