Yea, here is a tip. You have no experience smoking, so you are most likely not doing it right. You can't just suck and blow like Bill Clinton. You need to inhale. Here is how you can be sure to inhale. Hit the joint. Before you exhale, breathe in. The smoke will then be carried into your lungs. You will know you are doing it right because the smoke will cause you to choke a little, it will scratch your throat, especially being a newbie. Hold the smoke in for a few moments, then you exhale. You will most likely have to cough, but don't worry, that is totally normal, and I always used to feel like coughing got me higher. If the smoke is too harsh on you, you could always consider investing in a vaporizer, those hits are smooth as silk.

So remember, inhale. If you inhale and you are still not getting high, well maybe you are the rare case that is unaffected by THC. Or you are buying fake weed and your friends are liars. Hope this helps.
