5 Although the prevalence of current cigarette smoking among US adults in 2018 was at a historical low of 13.8% (marking a decline of more than a third from the 1965 reported rate of 20.9%), the relative risk of all-cause mortality from smoking has increased in both men (from 1.76 to 2.33) and women (from 1.35 to 2.08) during the same time interval
Since 1965, smoking rates among women have dropped by about 59 percent, compared with a 66 percent drop among men
Though what is considered unusually low fuel moisture content can vary with local vegetation and conditions, general guidance provided to wildland fire fighters is that fine fuel moisture contents between 5% and 7% are associated with very high ignition probabilities, rapid buildup, and loss of control, and fine fuel moisture contents below 5% are considered critical fire conditions [50]
