What is the word of wisdom?
We don't drink or do drugs. Why? Because Heavenly Father has simply asked us not to. Yes, back in the day and as stated in the Bible, they did drink wine. But since that was a very long time ago, the church as evolved and so has the church. God has revealed through our prophets and said he doesn't want us to partake of those things because we are to treat our bodies like a temple. Keep it pure and clean. Do people drink who are Mormon? Do people do drugs who are Mormon? OF COURSE! Everyone has their free will and can do whatever they want. Temptation is real, the world is real and people, EVEN MORMONS, are human and make mistakes. Can we be forgiven of these things if we choose to repent? Of course! If you go to Heavenly Father and ask with a sincere heart, anyone can be forgiven, no matter what you have done in your past.
