Whether its 'right or wrong' really depends on the morals of the person debating the subject. Some believe weed should only be used as a medical aid while some believe it doesn't hold any medicinal qualities; as long as you have evidence to support your claim of what side your choosing you shouldn't have a problem.I can give you some sources for both sides if you need some just PM me :D
