If banning marijuana is about "protecting" the Thai people and culture then alcohol should be banned first. Smoking marijuana has never killed anyone-yet alcohol (which according to a simple search) kills 20,000+ yearly with millions addicted-including over a million youth. So if it is NOT about safety-then it has to be about money. If just "weed" was sold, no edibles or other forms beyond just the flower there should be no social issues. It has been marketed this way for 1,000s of years without major problems.
