Canada.com has an article on the rising use of meth among teenage girls. Apparently, young girls are using it to help them lose weight. I have two points I want to make on this topic.
My first point is that our society needs to change its focus from outward appearance to inner beauty. This will probably never happen; external focus has been a problem in the world since the dawn of time. Anorexia, bulemia and now drug use are only the most recent problems. There used to be fat farms (yes, fat was in once) and corsets into which you could squish your guts and cause permanent damage to your body. It is my belief that every parent has the responsibility to teach their daughters (and sons too, but let's face it: this is predominantly a girl's issue) that their beauty should not be skin deep. Strength of character, integrity, wit and intelligence are far more valuable and will take you farther in the long run than a pretty face will.
My second point is on drug use. This is an issue that hits close to home for me, so I will not be writing very much about it. I just want to say that until you have seen someone under the effects of meth, you can't possibly understand just how bad it really is. Don't let the article fool you; although it may be cheaper per hit than cocaine or heroine, it is equally as devastating (if not more) and in the long run will consume just as much of an addicts monetary resources. The effects on the brain take time to repair, if they can be repaired at all. Given the drug's growing popularity however, it would be naive for a parent to assume that they can protect their child forever. All you can do is arm them with knowledge and pray.
Give your children backbone. Teach them to resist peer-pressure, to avoid group-think. These, and prayer, are your only weapons.
