A group of U.S. lawmakers wants stricter rules for dissolvable tobacco products. Other advocates say smokeless products can lessen the disease, death and disability caused by smoking. Jennifer Ibrahim, associate professor of public health at Temple, says that if done properly harm reduction is a good idea. "I think that everyone in the business of smoking cessation is realistic, that people can't quit cold turkey, but you don't want to send the wrong message: that nicotine is safe at any level, because it's not," she said.
