A few tips for this lady:
1) Put down the bottle. Alcohol can destroy families, weed generally won't, unless the government destroys your family because you happen to smoke weed (which it is more than happy to do), but that's another matter.
2) Only hit the kid if he really really deserves it, if you want it to have any disciplinary impact. If you beat your kid over inane things like that it'll just fuck up his head later on in life. There's a fine line between hitting your kid to teach him a lesson and unexcusable domestic violence, but unfortunately a lot of drunkards in the Bible belt just can't see it.
3) What were you even thinking, asking your 11-year-old how to roll joints? If he knows how, he shouldn't. You should be able to do better than him, even if you're too drunk to think straight.
4) Get a frickin bowl or bong or something. They require hardly any coordination.
