I am the weed, especially with a handle like that, I think you're in the wrong place. Not all people who enjoy weed are deadbeats, just like those who enjoy a glass or two of wine are not. Do you find drinking immoral too?
Also, a lot of successful people do use drugs, probably moreso than these "deadbeat" types, especially marijuana. Just as an example, I know Chainer mentions this in here frequently but he's doing his undergrad with a double major and doing AWESOME, and I have a Master's degree. We are good people, we do good things for others, and I know we have helped those in need. While I may not be on as friendly of a basis, Vader is not a deadbeat either, nor is Swerlz, and our newest addition to our CD staff, papasomni is a bit older and very successful and comfortable. And guess what? We all smoke pot. We are all pretty open in here, and this is the CD staff, meaning we dedicate time to writing and moderating about cannabis here on BL. You really need to rethink why "weed is immoral" if you're going to hold that very stubborn, close-minded opinion.
Yes, there are plenty of deadbeat immoral losers who smoke pot, but that does not imply that everyone who smokes pot is a dead beat immoral loser. (To use your own word "immoral" which I don't use frequently, nor agree that drug use is any more immoral than sex for pleasure or indulgence in any substance, even caffeine, under your guidelines apparently.)
