You probably shouldn't make a habit of it when you're so young, I smoked for the first time last year after I turned 16 (I'm 17 in less than a month), this year I've smoked occasionally with friends and on my own, but made sure that it wouldnt get in the way of my school life.
Now I'm finished school, so its all good. But yeah, Let weed revolve around your life, not your life around weed.
I just ask you to use it responsibly, and not give weed, and its users a bad name.
That said and done, Feels good doesn't it?
