Marijuana Legalization in New Jersey Discussion

I’m working on a health & medical question and need an explanation and answer to help me learn.

New Jersey voters overwhelmingly approved the referendum about legalizing recreational use of marijuana for adults, and now the state must determine what legalization will look like.

So, how will the legal sale of marijuana be conducted? Could someone walk into the local corner store and buy it, or will there be specific, state-regulated facilities that can sell the plant?

Intoxicated driving is a serious concern that comes with legalization. How do you think we will prosecute or identify people who drive under the influence of marijuana?
