Dear friend,

I know that you are drug addicted. I want you to stay away from them as they are very dangrous. Here are some tips I would request you to follow some tips mentioned below.

1. Learn to Deal With Life’s Pressures  The inability to deal with normal life pressures is one of the major reasons that drive people to drugs and alcohol. For many people, drug and alcohol consumption is a way to escape the harsh realities of life. Learning to cope with life’s pressures will go a long way when it comes to helping people stay away from drugs and alcohol.

2. Don’t Give in to Peer Pressure  Some people, particularly teenagers and young adults, experiment with drugs just to portray a cool image in front of others. They do it to fit in among their circle of friends. Some kids wrongly believe that doing drugs or consuming alcohol will make them more acceptable and popular with other kids. Not giving into peer pressure can and will prevent drug addiction.

3. Develop Close Family Ties  Research indicates that people who share a close relationship with their families are less likely to become drug addicts. The guidance and support provided by the family makes it easier for a person to deal with life pressures and stay away from all types of harmful substances. The same is true for having a close relationship with good friends that are responsible and trustworthy.

Please follow them as I only wan't the best of you.
