Thanks for your replies. I don't know - I don't think my friends are the "wrong people". Heck, they've never influenced me to try anything thus far. This urge came about of my own curiosity, not their pressuring me to try it. In all honesty, I've had the same best friend since 4th grade. Even if I wanted to stop hanging out with him, I wouldn't - high school is winding down. I'd rather spend more time with him, not less.

I cannot take ANY chance of my grades being impacted by this, though. The first two years of high school included Cs and a D here and there in sophomore year. Making all Bs now, I'll be lucky if I can get in to any school. That alone puts this whole curiosity to rest.
