Phantom I couldn't disagree more. Have you ever smoked pot? I have--not as much as I used to, but I certainly have plenty of first hand experience. You are partially right, you CAN throw up from weed, but that is only if you get totally blown. It only happened to me once, and that...... Well, you probably don't care, but suffice to say it was a lot. And your point about how once you smoke MJ you're faded is not true. As a matter of fact, there are lots of people who smoke pot on a regular basis and get through the day. For instance, when I was at high school, I would normally smoke a joint or bowl with some friends before school, and still work on homework and shit like that. If anything, its HARDER to be drunk and get through a day because, well, your drunk. The biggest effect MJ has is sleepyness and the munchies:)
There aren't too many clear-cut stages of high, because its the same throughout. You get relaxed, you get more relaxed, you get sleepy, if you smoke a shit-load of high grade stuff you will hallucinate, but thats it.
And unlike alcohol, people rarely get violent or mean when they are high,(and don't tell me different, my mom is an alcoholic, so I would know).
As for your point on cops pullng you over....... Please, have you smelled pot? It is highly detectable, and if you are smoking in a car it would be impossible not to tell. Not to mention red eyes and big pupils. They can make them walk the line anyways, its not that different. Like I said, the good effects of weed and alcohol are basically the same.
