Welcome

You can get garden variety health advice from the daily newspaper, the "health" section of most book stores, and of course thousands of web sites. I'm hoping to present thought provoking and maybe change provoking thoughts about individual and community health. This blog is not just what to do about health, but how to think about it. I'm looking forward to an exchange of ideas with readers. July, 2010

The Worst Drug

This week I came across a news review of a report published in the British medical journal, The Lancet.  The report was about an effort to rank the harmfulness of 20 commonly abused drugs.  Rankings were done by 15 experts on drug addiction, policy and toxicity, all from Great Britain.  They used a complex scoring system which considered physical and psychological harms to the individual user as well as harm to society at large.  The number of users in British society was part of the calculation.  The findings of the project caught the attention of news organizations because we are programmed by the drug warriors to think of cocaine, heroin and methamphetamine as the worst drugs.  Instead these experts determined that alcohol was the most harmful drug.  Here are the rankings:


The upshot of the report is that government policies which categorize drugs for the severity of restrictions have limited connection to the actual harm caused by specific drugs.  For example, Ecstasy and LSD are highly restricted and regulated, though not very harmful, while alcohol, the most harmful drug, is restricted hardly at all.

In the U.S. we have a parallel circumstance.  In 1970, the U.S. Congress passed the Controlled Substances Act, which created categories, called schedules, of drugs according to their potential for harm, their addictive risk, and whether or not there are legitimate medical uses.  For a good cure for insomnia, try this link for details on the Act.  You may need a stimulant to get through the text of the Act.  Since the original passage, there has been debate regarding the validity of the placement of various drugs.  For example, Schedule I, defined as the group of most dangerous drugs, includes heroin, but also marijuana and LSD.  While there is no argument that heroin addiction is a destructive lifestyle and a blight on the communities in which addicts live, the case can be made that use of heroin is made much more harmful because of well-intentioned government policies.  Today, it is hard to find an expert voice who will say that marijuana is a particularly harmful drug.  Notably absent from the schedules of the Controlled Substances Act are alcohol and tobacco, which at the time, were not considered drugs by most people, including members of Congress.

In my view, the findings of the British experts are paralleled in the U.S.  Our greatest drug problem is alcohol.  Tobacco kills about five times as many people as alcohol, but smokers live entirely normal lives until about 25 years in they get life-threatening chronic illnesses like cancer, heart disease and chronic obstructive lung disease.  There are almost no social harms caused by tobacco, and in fact, there are social benefits in employment and trade.  Alcohol doesn't kill as many people, but destroys the user's life once consumption passes the moderate level of drinking.  This leads to serious and worsening health problems, loss of employment, family turmoil and breakup, domestic and public violence, highway accidents, homelessness, poverty, huge productivity losses and treatment costs.  To be fair, alcohol has some medical and social benefits.  The evidence is strong that moderate alcohol use, particularly with wine, has medical benefits, though this fact does not mean that everyone should drink.  In addition, alcohol has social benefits in employment, trade, and tax revenues.

The fact that alcohol is used by two thirds of adults, and that there are some health and social benefits, makes health promotion messages and policies complicated.  Health communication directed at the public doesn't incorporate nuance well.  Effective communication needs to be direct and unequivocal, and for this and other reasons, we struggle as a nation to educate and influence to find benefits from no more than moderate consumption while trying to block all the destruction alcohol can do.

We are soon going to face this with marijuana as well.  The momentum behind legalization of that drug seems to be gaining speed and strength in states and local communities.  The challenge will be to build up public precaution about the potential hazards without blocking the real or imagined benefits.

I think availability can be defined two different ways. I don't think they look at alcohol as user volume. However, alcohol does have a significant impact when you take into account bar fights, assaults, alcohol-fueled rages, hazing deaths, etc. The availability in group settings does create an atmosphere for problems developing.Thanks for the information.

As with the case of tobacco and its harm, it will take some more years of research to back up a powerful public interest in restricting use of alcohol, leading to restrictions at local level. Soon, powerful companies such as Brown-Foreman will be on the losing side of this battle.
