Mmmm, bud has its uses. I was a heavy stoner in years 10 and 11, i fried my short term memory but still did pretty well.
In year 12 I've found i had to find a balance between bud and work, I only smoke every fortnight now, i miss it a bit, but i got after the HSC for that
Its amazingly good for stress, nothing beats a game of COD and a cone.
