How Iceland Got Teenagers to Stop Drinking and Smoking
In Iceland, scientists identified the biochemical processes that lead to addiction and, over 20 years, drastically reduced the number of teenagers who smoke or drink alcohol. This was reported by Mosaic Science.
Interestingly, people can become addicted not only to smoking or alcohol but also to cars, money, or certain types of food. Icelandic schoolchildren were offered free workshops in any sport or art form they wanted to learn, which were included in the school curriculum.
Scientists hypothesized that such activities could produce the same emotional effect on teenagers as alcohol or cigarettes. The state funded additional activities three times a week. Each teenager was offered to participate in the program for three months, but many continued attending for five years or more.
“Dance, music, painting, or sports also trigger biochemical processes in the brain that help cope with stress,” the researchers noted.
To tackle nicotine and alcohol addiction among teenagers, the government also had to change the law. Iceland banned advertising of cigarettes and alcoholic beverages and created special parent organizations that, together with schools, helped students deal with psychological issues.
“It’s surprising that similar methods are still not widely used in other countries,” scientists point out. In the mid-1990s, Icelandic teenagers were among the heaviest drinkers and smokers in Europe. Today, Iceland tops the chart of European countries with the healthiest lifestyles among teenagers. The country managed to reduce the number of teens who regularly drink alcohol from 48% to 5%, and smokers—from 23% to 3%.

🤔 The impact of this model is not established, and what works in this small country is not necessarily replicable elsewhere.
osvita.ua links to it's main page, but the pic is also on several social media on the same topic or not,

We did find that this Icelandic Prevention Model (IPM), was indeed implemented in the late 1990s:

Several studies and experiments worldwide have attempted to replicate and analyse this model:

However, some questions remain:
-The impact on the control group by the Icelandic alcohol policy is unclear.
-The exclusion of 5 communities raises questions about fidelity and dosage of the intervention, as well as a high dropout rate.
-No analysis of baseline differences such as socio-economic status was conducted.
-The measured outcomes do not correspond to the intervention components or the logic model.
-The analysis does not prove a causal relationship between the intervention and the results.
