Those numbers measure the percentage of teenagers who regularly use illegal drugs of some type. Just within the last month, 50 percent of teens report drinking alcohol with 37 percent saying they had been drunk on at least one occasion. Alcohol kills 5 times more teenagers than any other drug which are mostly from accidents.

It's scary to think that our young people are being exposed to drugs at a much earlier age, and they are much more susceptible to peer pressure. When their friends offer up drugs, they often don't have the strength to say no, so they begin the frightening cycle of drug abuse.

In recent years, much has been learned about the health effects of teen drug use. Drugs are readily available to those who choose to use them in either an "experimental" way or to those who are chronic drug abusers. The consequence of such use, even causal use, can be devastating to both the user and to the user's family members.

But, teen drug use is costly to more than just families. It is especially costly to our society as a whole. Youth's immature physical, emotional, and psychological development make them MORE susceptible than adults to the harmful effects of drug abuse.

In the 7 years that the National Center on Addiction and Substance Abuse (CASA) at Columbia University has published the National Survey of American Attitudes on Substance Abuse, results have indicated that teens and their parents view drugs as their biggest concern. The health effects of teen drug use can vary, depending on such factors as frequency of use, the kind of drug taken, how much is taken, how quickly it gets into the brain, what other drugs are taken at the same time, the differences in body size and chemistry, the length of time the drugs are used, and other components. Why do teens use drugs? Of course, peer pressure is a huge factor, but they succumb to peer pressure for many other reasons. Low self-esteem, depression, anxiety, inability to express feelings, lack of control, and feeling like they have to live up to unrealistic parental expectations all contribute to the teen beginning to use drugs. Plus, many teens are affected by watching their parents' own addictive behaviors.

Trying to deal with issues revolving around the family upon such an escalated level proves extremely difficult when children of alcoholic parents cannot even function normally regarding their own lives. This situation often spawns a codependency syndrome that follows the child throughout his or her entire life; codependency has long been found to be a significant indicator of alcoholism.

And, believe it or not, parents who overindulge their children may be dealing with a teenager drug user before they know it. Many parents spoil their children not only with toys and gadgets but also by not setting limits for them. That freedom leads them to make bad decisions about their lives which includes drug and alcohol use.

If your teen exhibits six or more of these signs over a period of a few weeks, he or she probably is using drugs. You need to address it as soon as you suspect this to be true. The most effective tool against teen drug use is communication. When you pair open communication with education, you have double the ammunition to fight drug use.
