Does Marijuana raise or drop blood pressure.

Does Marijuana raise or lower blood pressure? (Or does it do nothing at all to it?).

Marijuana users frequently get ‘red eye,’ which I believe is caused by dilation of the blood vessels. If this dilation occurs elsewhere in the body, it could lower blood pressure.

Worst drug for raising blood pressure is crack.
