I personally only smoke weed as a social thing, such as at motives or if I am out with mates. I never feel the need to MUST smoke a zoot. I believe this is mainly because I never put any sort of baccy in my zoots, they are just straight weed. I do not smoke cigs and refuse to smoke them, even at a social event.
Personally I think it should be legal at a certain age (18) as its not as bad as people play it out to be. Also if it was made legal, it would be able to be controlled easier, along with stopping shitty dealers selling bud rock in their weed.
If it was legal, laws would need to be introduced to stop driving whilst high, etc. I cannot legally drive yet, but I know I won't smoke and drive, as I have ridden a bike and an electric scooter whilst chonged, and the only way I can describe it would be as a slide show...
