Thats def not true u can get high off of smoking leaves not a crazy ass high but you can, it depends on strains and the thc on the leaves. Thc can fall on fan leaves and how do u think some hash is mad from???? just straight buds NOOOO? I have a whole shit load of leaves that I collected from my harvest and there covered in THC. I even read some where when I was picking the AK47 seeds that it was known that even smoking "male leaves" on that strain get get you a slight buzz.....never tried it but know someone that did and they did get a buzz off of it
