Combining narcotic drugs such as fentanyl and heroin can be deadly because? a. you feel like you can do anything b. it stimulates the heart c. they are narcotics as well as depressants and can depress your breathing

C.

Because mixing narcotics isn't good and could cause a bad outcome if you think about it.

For example, if you mix cake powder with only oil, milk, and sugar, then forget the eggs. You already know whats going to happen it doesn't cook right and the outcome is bad.

So is the not being able to breath right, b/c of mixing narcotics.
