Wow!!
All my life, i have seen canabbis as a bad and hard drugs, even though i know some hard drugs that are quite medicinal. This your post is an eye opener.
And about being free to use, i think the government is just restricting it because , if its free to consume, many will abuse it by taking it in excess and might cause serious side effect that may pose life threatening condition to human.
Thank you @doitvoluntarily
