Allowing MJ with other drugs is a no brainer. I also very glad the author found a way to help his son and it should be let alone. However, saying things like that is not very responsible:

> But Lester Grinspoon, a psychiatrist and professor at Harvard Medical School who has been researching cannabis since the 1960s, reassured me that the worst we could do was make our son fall asleep.

One study had shown that even if there is no long term effect on adults on IQ, teenagers experience on average 10% less IQ than no consumers - even after stopped completely taken it for years. Another study has shown that if you are DNA predisposed - less than 3% of the population - MJ can induce schizophrenia reshaping the brain long term even after years after taking it. I don't fully get this is not common knowledge. Maybe, this is not hype enough and people want to not being perceived as reactionary. But, facts are facts.
