A new study by Duke University of North Carolina seems to have proven what we all suspected: excessive alcohol consumption during teenage years damages the brain permanently.
Specifically, alcohol causes permanent damage to the hippocampus - the part of the brain responsible for memory and learning - and the danger period extends to the age of 20.
This study puts the research on cannabis into perspective as it shows that it is not only illegal drug taking that may cause brain damage. It was claimed recently that exposure to cannabis in teenage years can diminish IQ.
The UK government's own scientific advisers have stated on many occasions that if alcohol were invented today it would, under the current guidelines be catagorised as a Class A drug.
As more rigorous scientific research is carried out it becomes clear that if governments choose not to ban alcohol then there can be no reason to ban cannabis. Law, especially a law that imprisons thousands of people every year, must be based on logic and not on financial expediency or political bigotry.
