There are several reasons that motivate youngsters towards alcohol or drugs. Curiosity, need for adventure and excitement, experimentation are the initial causes of motivation. Some youngsters start consuming drugs and alcohol in order to overcome negative emotions such as stress, pressure, depression, frustration etc while others do it to be in sync with the modern society or due to peer pressure. Several mediums like television, internet, newspaper, movies etc. are also responsible for promoting the idea of alcohol consumption to the younger generation.
The measures that can be taken to prevent this can be:
(a) Parents should understand their children and be supportive. They should motivate and try to increase the will power of their child.
(b) Parents should educate their children about the ill-effects of alcohol. They should provide them with proper knowledge and counselling regarding the consequences of addiction to alcohol.
(c)  Children should be encouraged to devote their energy in other extra- curricular and recreational activities.
(d) Proper professional and medical help should be provided to a child if sudden symptoms of depression and frustration are observed.
