Levamisole also affects acetylcholine receptors throughout the body, which can boost heart rate - and studies of cocaine users show that they associate jumps in heart rate with getting high, spurring good feelings even before the drug hits the brain. A cut that accelerates heart rate might make them think they're getting the real thing. In the brain, levamisole may affect the same acetylcholine receptors activated by nicotine, another addictive drug that raises dopamine levels - which may be another clue to levamisole's lure.

...study by researchers at the University of California, San Francisco (UCSF), Stanford University and Columbia University shows that even a modest decrease in daily salt intake can lead to dramatic health benefits. The authors documented an annual drop of as many as 120,000 cases of heart disease, 66,000 instances of stroke and 99,000 heart attacks caused by high blood pressure after a 3-g-per-day reduction in sodium.

...team conducted a computer-based analysis to determine the impact of a 3-g-per-day reduction in sodium intake on rates of heart disease and death. They also calculated the cost savings emerging from the amount of disease that would be avoided because of lower blood pressure. The conclusion: by cutting salt intake nationwide, the U.S. could save $10 billion to $24 billion annually in health care costs...
That's a serious amount of money, but it's the health benefits that are even more stunning. Using data from previous clinical trials on salt intake and blood pressure, the researchers found that reducing sodium by 3 g per day would be as good for the heart as cutting tobacco use by half, lowering one's body mass index 5% or taking statin medications to lower cholesterol. Even more surprising, cutting salt by 3 g per day was as effective in reducing death rates among people with hypertension as taking medication to control blood pressure. (See the 10 worst...
