Higher than anything else? I doubt it. But really good? Definitely. I think this is because the volume of smoke (and thus amount of THC) is so great and is ingested in such a short period of time (you rip a bong and you take the full hit in quickly). Bottom line, you can pull bigger hits on a bong and thus get fucked up faster.

Some of my best/highest experiences have been after ripping a bong. Granted we tend to burn that shit to the ground for bowl after bowl until either there is no more weed, or no one is willing to pack another bowl.

If I were trying to get really blazed I would look into purchasing a vaporizer. Personally I have never used one but the general idea is solid. It's apparently the most efficient way to smoke cannabis. However I do remember reading that the CBD/CBN isn't used with a vaporizer. In this case I've heard of people vaping their buds and then using whats left (after vaping) to cook with. You essentially smoke the THC and cook/eat the CBD/CBN. (this is personally untested, sorry )

I recently made some brownies. We threw about 8 solid grams of high mids into one batch. (in fact we still have some butter remaining so not all of the THC from the 8 grams was in the brownies.) I ate 2 and was blazed for close to 8 hours. We also smoked what appeared to be about a 2.5 gram L-joint skillfully rolled by a friend of mine. All of this was prior to an Easy Star All-Stars concert which, needless to say, was out of the world.

If you've never experienced a brownie high then I would suggest doing this to get really high. My entire perception of the world was altered. And it was the most enjoyable thing ever.

My 2 cents.
