Not everybody wants to abstain from having a few drinks, or even a joint for that matter. Society is changing, we aren't all from the 50's and 60's. Let people live their lives, just because somone has a few beers during the weekend or has a couple of joints certainly doesn't make them useless, stupid or lazy.
Smoking a joint can really cost you your life? I think thats hilarious. Reminds me of that movie reefer madness, and the shitty propaganda put out claiming that people who are stoned go around sexually assaulting women.
I don't see how advocating the use of alcohol or cannabis highlights issues that somebody has. Who hasn't needed a stiff drink after a tough day? We have one life to live, and I think it is completely absurd that an outdated set of beliefs dictates how people spend their own time, in their private homes. To put it plainly, restrictions don't work and they won't EVER work. Even the alcohol policy in the states has led to teen binge drinking. One report on CNN even claimed that 1 in 5 units of alcohol sold, are used by a minor. The state isn't here to be your mom. You can make your own decisions about what you put in your body, and how you spend your free time. The government should fulfil it's sole purpose of implementing educational programs and warnings about using such substances.
