الادمان على المخدرات لا يقتصر على انواع محددة من المخدرات حيث ظهر حديثا انواع مختلفة من المخدرات تؤثر تأثير بالغ على الاجهزة المختلفة من الجسم وتدمر خلايا المخ والجهاز العصبي المركزي وقد تصيب المدمن بالعجز او السرطانات المختلفة حسب نوع المخدر , لا شك ان المخدرات تصيب كافة الانواع وطبقات المجتمع ولاترحم صغير او كبير
علاج الادمان من أضرار المخدرات والكحول والدخان الكثيرة على حياة الأطفال والمراهقين
ولادة الأطفال مدمنين على المخدرات أو متأذين بالتعرض للكحول وهم في أرحام أمهاتهم،
ثم يعيشون بعد ذلك في فقر وفوضى اجتماعية مع الإهمال والاعتداءات
والتشرد لأن آباءهم يعانون من المخدرات أو الإدمان الكحولي،
ثم التسرب من التعليم
واحتمالات متزايدة للأمراض النفسية
وهم عرضة أكثر من غيرهم ليكونوا ضحايا العنف والحوادث وأذى الذات
وأولاد المدمنين هم المرشحون الأوائل لدخول عالم الإدمان على النيكوتين والخمر والمخدرات فالبيئة مشجعة والمواد متوفرة وتقليد الكبار والأصدقاء يسير في هذا الاتجاه
وجدير بالذكر أن الاستعمال المؤقت /التعاطي/ يشترك مع الإدمان في الأضرار
