Help me!!! stimulants and depressant!?

Question

well my question are:

how stimulants alter the human heart rate?

and how does a depressant impact heart rate?

Answer 1

stimulants like, crack, caffeine and meth shrink your blood vessels so your heart has to pump harder, essentially it increases your blood pressure

deppresants are the very opposite, they decrease your heart rate, like mary j, narcotics, sleeping pills etc.

***** please for no reason should you ever mess around with these very illegal and very dangerous drugs. Dont even think about taking anything starting with stimulant/deppressant with out a specific doctors prescrition made out to you.******
