A question about seeds and growing

I am new to all of this and also have a black thumb. I am signed up for a growing class but on a waiting list because it's the most popular one around. A few night ago a friend stopped by with some fine bud. He left a pinch on the tray and later when I was about to share some with hubby I noticed a seed in it.
Can I sprout this seed? If so, can someone share a good link with step by step instructions?
