Do Puffers Cause Dizziness And Elevated Heartbeat?

i quit smoking for about 3 weeks now after smoking for about 2.5 years. Im experiencing shortness of breath, rapid heart beat, a little dizzyness, I also had a mild asthma when i quit and im still using the puffers even though i normally have no use for them. I know these are normal symptoms of quitting, but is there a connection with this medicine and my physical symptoms?
