It definitely amps up the heart.
So much so that people have had to use Atenalol and other stuff
for a while while trying to get off it. If you go to a re-hab for alcohol
O.D., you get put on a librium drip and a heart moniter because
the risk of heart attack is very high when detoxing.
I would say stick to an opiate or combustible leafy substance if you're
worried about your heart
