Not addictive? No. It is a mental addiction vs. a physical addiction. Physical addiction is the type of addiction of crack or tobacco. Your body becomes dependent on the drug and you suffer fierce withdrawals if the supply is cut off. Mental addiction is where your brain becomes used to the feeling a drug gives you and slowly becomes dependent on that drug. It can potentially get to the point where a cutoff can lead to insanity. That being said I wouldn't smoke it wether it is legal or not for ethical reason.
