I do cook with it and have become a big tincture fan in last year. Yes, I too have always had a cast iron stomach. No major tummy ache, a few times a little indigestion but I've had worse from beer and brats.
If I were going for the big buzz I would use some cooking method for my delivery system, or a big dose of tincture. At this point in my life I am not a very heavy smoker so perhaps my low tolerance is a factor. And you can't beat the simplicity of preparation. As stated I usually eat this in the AM and I use this method more as a sedative continuous buzz, then a Friday night (or Tuesday morning) let's explore the inner realms, type of experience. Smoking with eating raw weed amplifies the high of each delivery method. And like many first time smokers I wasn't sure what to expect and only felt a little buzz my first time, but it seemed worth experimenting with.

The discovery of the very dry pot has seemed to be the big key for me.
I have also discovered that smoking the first half of a joint, then eating the second half will give me the dual high of smoking and eating, as the smoke levels off and mellows, you started getting that heavy head and body buzz that comes from oral consumption. I know it sounds gross, but it works for me.
I have enjoyed your thread and flameon's and hope to do some experimenting soon. I'll post my results.
