While I've never been high myself, I can certainly sympathize with those who feel pot should be legalized. There's a ton of people in my family who smoke weed, including my father, my brothers and sisters (some of which are working on their Ph. D's and Master's degrees, etc.), some cousins, some uncles and aunts, and every single one of them are positively contributing members of society. I'd consider marijuana MUCH less harmful than alcohol. In fact, my uncle cured his Lyme disease with pot butter, it's just a shame he had to do it in hiding.
It's really too bad that a largely harmless and extremely common drug may have to ruin Sheets' football aspirations, regardless of his otherwise shady character.
