does marijuana elevate blood pressure
Lung cancer- marijuana smoke contains more cancer-causing chemicals than tobacco smoke. Smoking three to five marijuana joints a week is equivalent to smoking 16 cigarettes every day. Smoking one marijuana cigarette has the immediate effect of increasing heart rate and blood pressure as much as 50 percent. Marijuana increases the amount of toxic carbon monoxide in the blood, thereby reducing the amount of oxygen which reaches the heart. Increased blood pressure and changes in the blood vessels are reflected by the typical red or bloodshot eyes of the marijuana user.
