Eskimospy actually had a pretty definitive answer to that: People who squader their EBT allotment today don't get extra largesse, why would we assume they would if the hand-outs are handed out by different rules? (I have been agreeing with Eskimospy a lot lately; I obviously need to get more sleep.

)
Zinfamous makes an excellent point though. We conservatives (or at least, we on balance non-leftists) do advocate self-sufficiency, less government, and more individual liberty. These things are all in conflict with program restrictions which ban "sin" items "for their own good." I too like these restrictions, especially where these funds are earmarked for the support of children, but he is correct about the conflict. I should have caught that myself since I have that exact conflict. (Especially egregious since I KNOW how people get around these restrictions to get their beer and ciggies, and I KNOW that these methods leave even less for the children.)
Having been reminded, consider me chastened, and I'll flip my support toward individual liberty. Even though I can support more infringement on that individual liberty when one is on the dole, in the end, offering these charity cases the right to make their own mistakes might give them enough pride to learn good decisions. Can't be easy to go through life knowing that society considers you too stupid to be trusted with your own grocery shopping.
