Considering how much a person gets from welfare, if they have enough of it left over to spend on vices then they very likely have enough cash coming in from other sources to just use that instead. And if they don't, they likely have friends that will trade cash for the benefits. This will fix absolutely zero. In fact, it'll make it more difficult to track when people are abusing the system, so it'll be even harder to fix the problem.
If this somehow passes I will forever lose hope in government, because they are obviously too stupid to realize when they are wasting time and too callous to actually deal with the real problems we have in this country.
