This article saddens me.

The "Addiction" section addresses "teenagers" and those in "school". The "The developing brain" section also deals with "teenagers", and fully admits, "The adult brain appears capable of recovering from chronic pot use in a few weeks." The proposed legislation deals with limiting access to underaged people.

The "Mental Illness" section says, "The drug’s relationship to depression and anxiety is still up in the air; the science has not established a causal relationship between the two." IOW, even the "causal relationship" is nebulous.

The "Driving while high" section's 'concerns' are also addressed in the proposed legislation using heightened enforcement.

The "Your lungs on pot" section utterly ignores that close to half of usage is vaporizing (where there is no combustion), not smoking. And about half of the remaining usage is edibles.

Sorry, but this article deals with "substance abuse", not merely 'use'.

No wonder there's so much confusion.
