Ask HN: How many of you guys smoke weed?

I doubt I will get a huge answer on this, but I am curious. I personally never got into the smoking scene and find the smell to be horrible. My brother on the other hand spent a good year or two smoking and what I felt to be acting dumb. His claim to fame was that many successful people he knew smoked. However, while he smoked he really didn't do much, wasn't productive and ultimately ended up having to "restart" school and his career.

When I find out that someone smokes I am usually surprised unless they fit the stereotypical hippie look, doesn't do much and spaces out in mid conversation. I just read through a different post where a couple people outlined their day to include pot and it got me thinking afterwards.

So HN:

Do you smoke? If you do, why and do you find it beneficial? If not, why and what do you think of those that do?
