Weed is wasted with joints though if you share them (and alone too) they burn relatively quickly compared to other methods of smoking. lots of weed gets burned that doesn't go into your lungs.

And the hits aren't as big also. Part of getting high is how FAST the THC goes to your brain. You slowly become tolerant to it as you smoke. And it slowly leaves your body too. So bongs are my choice. Always get me the most stoned.

Plus, joints tend to make you feel the most burnt out, I've experienced.
