I Have a method in particular that I use to get really high.

-Smoke a medium sized bowl or even a small sized bowl in a medium to short amount of time.
-Take mix a drink of SoCo or Vodka or take your time drinking a beer
-Chill out for a while. play some games, play online, whatever to pass the time
-When you're coming down almost sobering up smoke a fat bowl. Usually I can't even get through the whole blow. I'm blazed outta my mind.
-Enjoy

This works best for me. Everyone is different. If I go all furious and smoke a bunch all at once.. I can only get so high, and I get bored and go to bed, or whatever. I gotta stage my smoking and make an evening of it, then I'm roasted like marshmellow. Give it a try. patience and chill.
