As a Canadian (translation: relative expert), I can say there's nothing wrong with the plant, or smoking it. There's everything wrong with defining your life by it, and allowing it to run your life. Now, you're probably thinking, "this is just another asshole who thinks weed is comparable to coke or meth, groups it in the same category, thinks it's addictive." I know it's not. But the potheads I know (daily smokers), by and large, while successful, allow it to take up too much of their time and money, and allow it to get in the way. It's like a cigarette smoker, except it takes two hours to buy the shit, because he has to smoke it with his dealer, and also has to cut it up, roll it, etc. And it costs a lot (the folks I know who smoke it heavily spend several hundred per week). So it does get in the way if you don't control it. I also notice that smokers are suspicious of everyone around them. Not just because of the effects of the dope, but because they have to always be worried about cops, or getting screwed by their dealers. So they don't like anyone, from their landlords, to randoms taking photos of them while they surf (true story, my buddy started mouthing off a tourist in Oregon this summer as we were walking along the beach, just because he took a photo of us without asking - and needless to say, we had no weed on us, given that we were in our wetsuits). Having said that, it can fit with the rest of your life, if you treat it like folks treat good wine or scotch - save it for weekends or appropriate occasions. I know a couple who are part owners of a tour company. They are irregular smokers but have their own stash (so they smoke enough). They have a view of the Rockies from their patio, a three-hole golf course in their yard, and a membership at a nationally-recognized (pro tour-quality) club. They're not failures. They also get really mad at me when I piss out of their hot tub. Lastly, there's a big difference between a regular smoker, and a once-a-year smoker. For the former, it's like having a beer - tastes good, maybe helps them feel a bit better. For the latter, they're higher than a kite, and a big liability. I know an accountant who's been high non-stop (smokes four or more times a day) for the last decade. He does good work.
