Now I have always hated buzzes, and stop smoking if I feel dizzy or light headed. I smoke slowly, and don't really cloud. When I stand up, I get super dizzy. I get dizzy if I stand up fast when not smoking as well. But it would compound it. Even hours later I would take a shower an hour later and the room would spin uncontrollably and get bad vertigo. It makes my migraines 10X worse than they normally would be, and they make my heart race like it wants to skip beats in order to catch up. Buzzes are actually painful due to the LBP.
this explains why my friend stopped smoking completely after he was diagnosed with LBP.
