Happens to me VERY often and has actually made me not smoke as much. It used to only happen after smoking like a gram of schwag or a couple good hits of nugz, but in the past year it has happened more and more often no matter the quality of the bud.

I also take a blood pressure medicine (it's an ACE inhibitor) due to a preexisting kidney problem, but I don't suffer from high blood pressure. I have the same symptoms when I stand quickly after smoking. I also get a rapid heart beat once the buzz kicks in. If it's too strong, I stick my head in the freezer for a minute or two and drink COLD water or milk. Within minutes I get to feeling better.

My thought with the head-in-the-freezer trick is that there is more oxygen in cold air, and since I smoke cigarettes too, more oxygen can only help. May just be a psychological trick I play on myself.

Anything you can put on your stomach should help, too. I find myself eating a piece of bread with peanut butter and a glass of milk (weed mouth CITY), and it really does the trick.

Don't let this get you down!!!
