nah. i've smoked a couple of cigarettes, a few years ago. a few friends smoke, and my mum smokes.. after trying for years to get her to stop, i thought i'd try it and maybe see what she likes about it. i can see why she might like it, but i don't like it personally. and i've done biology for the last 9 years, so i know in detail the effects it has on the body. it's not for me.
never tried weed so i can't comment on that.
