Of course, alcohol has the same effect. That is why there is no such thing as “harmless experimentation” for youths. You don’t let a child play in the street or with a sharp knife, because you know they endanger themselves. Teenagers may look all grown up these days, but they are still developing until well into their twenties and need protection. We also know that they still lack frontal lobe higher reasoning skills, and these develop the most in the teen years. So, i’ts a double-edged sword. They can’t judge the danger to their brains of certain drugs, and the same drugs are much more dangerous to their judgement than when they are ten years older.

Smoking a few joints with friends growing up may be the furthest thing from harmless for developing young brains, a new U.S. study suggests.
Teenagers who regularly use cannabis during their adolescent years may cause permanent brain abnormalities by using the drug, and increase their risk of developing serious mental disorders such as schizophrenia, a study published this month in the journal Neuropsychopharmacology, a division of the journal Nature, hints at.
The problems occurred in younger mice but not in older mice:
The study, conducted by researchers at the University of Maryland School of Medicine, examined the cortical oscillations in mice. Cortical oscillations (patterns of activity of neurons in the brain believed to underlie various functions) are very abnormal in schizophrenia and in other psychiatric disorders. Scientists exposed young mice to very low doses of the active ingredient in marijuana for 20…
