A lot of people simply don't get high their first time (or first couple times). I didn't. But also you're inhaling incorrectly if you just keep the smoke in your mouth. Inhale deeply as if you're taking a nice big breath of fresh air. Make sure it gets deep down in your lungs. Hold it for a good 7 seconds or so, then exhale. Don't get frustrated if it doesn't work your first couple times. Try smoking more and don't give up. When you get high you will know it and you will appreciate the effort you put in to get there.
