Only a diabetic would ask this question–why? Because most diabetics know and agree that current insulin smells like band-aids and novocaine. It’s an awful smell. You will be very pleased to know that Afrezza has NO taste and NO smell! And it’s painless. If you want an insulin that works in “real-time” this is the one for you. Keep the questions coming….the world needs to know about Afrezza!
