Why? Should "good parenting" also decrease the chances of a child drinking alcohol? Pot? Shrooms?
The apparent assumption here among many people that these substances are intrinsically bad is baffling to me. Where do you draw the line? Surely it can't be "legality", because several of the "schedule 1" drugs are completely harmless, and possibly even naturally occurring (in your own body!). If potential for bodily harm is the deciding factor, then we should be discussing alchohol "cures" looong before anything else. It is absurdly common and absurdly addictive.
"Disgusting" is purely a judgement call, which I admit may have some value in the case of smoking it. Fortunately there are plenty of other ways to use it. Vaporizers are great, and cooking with it... just yes. (You also of course do not need to make a 'habit' of it. I haven't used it in over a year myself)
As for antisocial? Well I can't speak for your experiences but for myself and the people I know it has been nothing but the opposite. Everyone needs to decide for themselves, including your kids.
Aside: Interesting fact about those restaurant/bar smoking ban laws: the reason they need to pass laws specifically for that purpose is because air filled with second hand smoke does not exceed the relatively very loose air quality regulations OSHA has in place. If that smoke were put there by anything besides smokers, nobody would say a thing.
