Currently, average apparent consumption of alcohol for all persons older than 14 is 10 percent higher than 10 years ago, and is equivalent to about 2.75 gallons of ethanol per person per year. Approximately 10 million adult Americans (i.e., 7 percent of those 18 or older) can be considered problem drinkers. Youthful problem drinkers, aged 14 to 17, are estimated to number more than 3 million and comprise 19 percent of this age group. In addition to the social costs, the economic costs to society as a result of alcohol misuse are substantial--an estimated +49.4 billion in 1977. Ten percent of all deaths in the United States are alcohol-related. Cirrhosis, which is largely attributable to alcohol consumption, ranks among the 10 leading causes of death. Alcohol use also is associated with cancer of the liver, pancreas, esophagus, and mouth. Alcohol consumption during pregnancy is associated with a wide range of possible harmful effects to the fetus--among them decreased birth weight, spontaneous abortion, and physical and mental birth defects. Drug misuse is also an expanding problem. There are some 16 million current marijuana users. The popularity of cocaine continues to increase--over 10 million Americans have tried cocaine at least once and there are an estimated 1 to 2 million current users. Misuse of barbiturates remains a significant problem with at least 1 million persons believed to misuse these drugs and the 30,000 estimated to be addicted to them. In addition, heroin addiction is still considered by many to be the most serious drug problem in the United States. Drug misuse leads to a number of social and health problems. Excessive doses of depressants can result in both physical and psychological dependence. The toll from heroin includes premature death and severe disability, family disruption, and crime committed to maintain the habit. Misuse of hallucinogens often results in emergency room visits. A special problem is the relationship of marijuana to automobile accidents, especially when used in combination with alcohol. While these events are disconcerting, progress has been made. National surveys indicate no changes in peak quantity consumed by teenagers 12 to 17 or in regularity of their drinking, between 1974 and 1978. Alcoholism mortality rates and alcoholic psychosis rates have shown little overall increase between 1950 and 1975. And similar encouraging trends have occurred in drug misuse. Several drug abuse data sources simultaneously have begun to reflect a down turn in use rates. These early indicators must be monitored overtime before conclusions as to their true significance can be evaluated.Nonetheless, the daily use of marijuana by high school seniors dropped from a peak of 10. 7 percent in 1978 to 7.0 percent in 1981. Daily regular cigarette smoking among seniors also declined dramatically-from 28 percent to 10 percent in the same period. The use of the hallucinogenic drug PCP also dropped markedly. Cocaine,heroin and sedative use among high school seniors remained relatively stable in terms of annual and lifetime prevalence, although the use of stimulants rose markedly. Of the 16 categories of drug use analyzed in the recent High School Senior Drug Use Survey, drug use in 15 categories was either stable or was decreasing(the second year of decline since the survey began in 1975).
目前,14岁以上所有人的酒精表观消费量平均比10年前高出10%,相当于每人每年约2.75加仑乙醇。约1000万成年美国人(即18岁及以上人群的7%)可被视为酗酒者。据估计,14至17岁的青少年酗酒者人数超过300万,占该年龄组的19%。除了社会成本,酒精滥用给社会造成的经济成本也相当巨大——1977年估计高达494亿美元。美国所有死亡人数中有10%与酒精有关。肝硬化在很大程度上归因于酒精消费,位列十大主要死因。饮酒还与肝癌、胰腺癌、食道癌和口腔癌有关。孕期饮酒会对胎儿产生一系列可能的有害影响——包括出生体重降低、自然流产以及身体和精神方面的出生缺陷。药物滥用问题也在不断扩大。目前约有1600万大麻使用者。可卡因的受欢迎程度持续上升——超过1000万美国人至少尝试过一次可卡因,目前估计有100万至200万使用者。巴比妥类药物的滥用仍然是一个严重问题,据信至少有100万人滥用这些药物,估计有3万人对其成瘾。此外,许多人仍认为海洛因成瘾是美国最严重的毒品问题。药物滥用会导致一系列社会和健康问题。过量服用镇静剂会导致身体和心理依赖。海洛因造成的危害包括过早死亡和严重残疾、家庭破裂以及为维持毒瘾而犯罪。滥用致幻剂常常导致患者前往急诊室就诊。一个特殊问题是大麻与汽车事故的关系,尤其是与酒精同时使用时。尽管这些情况令人不安,但已经取得了进展。全国调查表明,1974年至1978年间,12至17岁青少年的饮酒量峰值及其饮酒频率没有变化。1950年至1975年间,酗酒死亡率和酒精性精神病发病率总体上几乎没有上升。药物滥用方面也出现了类似的令人鼓舞的趋势。几个药物滥用数据来源同时开始反映使用率的下降。在能够评估这些早期指标的真正意义之前,必须长期对其进行监测。尽管如此,高中高年级学生每天使用大麻的比例从1978年的峰值10.7%降至1981年的7.0%。高年级学生每天定期吸烟的比例也大幅下降——同期从28%降至10%。致幻药物苯环己哌啶(PCP)的使用也显著下降。高中高年级学生中可卡因、海洛因和镇静剂的年度和终生使用率相对稳定,不过兴奋剂的使用显著增加。在最近的高中高年级学生药物使用调查分析的16类药物使用情况中,15类药物的使用要么稳定要么在下降(这是自1975年调查开始以来下降的第二年)。
