For me, this is really a situational issue:

If I'm alone, I'll usually end up just smoking out of a glass pipe. Occasionally I'll use the bong, without water. Rarely will I have a j or a blunt alone.

With other people, I also usually will use a piece, or multiple pieces. The bong filled with water or ice or both is used sometimes as well. Js and blunts don't normally make it into the equation, unless someone has some papers and suggests one. I can roll some solid js, but never done a blunt before. I find js and blunts to be messy and impractical for smoking in places where you don't want ash everywhere. I also find that js seem to leave a smell behind, where bowls and the like don't so much. But like SENSEFAIL said they're great when you're on the go.

Js are good in a rotation scheme (assuming a nicely rolled j and people who aren't gonna slobber all over it) because it bypasses the hassle of rotation of a bowl or bong. A j only needs to be lit once, whereas a pipe may need to be lit several times. There is no wondering with a j if it is cashed or still smokeable, as there is with a bowl. The j is easy to pass with one hand, as passing a bowl and a lighter can become cumbersome in the later stages of the session. If you drop the j, it could start a fire, but it won't shatter or spill a mess of bong water. Need to get rid of that j quickly? Save up some spit (if your mouth isn't too dry) or carry a bottle of water. Put the j out in a little puddle of spit in your mouth or put some water in your mouth and drop the j in, and swallow. Now nobody will find it. As you can see, the j has its advantages, but every method of smoking is different, and what is ideal for one person may be disliked by the next.

special case: I have weed, no papers, but I have cigarettes. Nothing is better than emptying the cig and re-packing it with tobacco and herb. I'm usually not in that much of a hurry to smoke, but sometimes you just gotta get high.


Question: Do you put tobacco in your js? Are you supposed to?

I usually don't put tobacco in my js. The only time I put tobacco in is when somebody else wants to or when I don't want to smoke an entire j.
