Smoking Weed? is What They Say is True That Weed is Bad?

I want to know how people felt since they stopped smoking weed? As a former pot smoker I seen some successful people such as doctors and lawyers admitting the use of weed in there college days. As for me I would smoke with 5 other friends. We would smoke on weekends go to school threw out the week. Well I smoked on weekends only. the other 4 other used to skip classes. They have become lazy and very desperate and depressed. is that a effect of smoking weed? When I wanted to go to a town center they rather wanted to stay in the room and smoke pot. they become desperate when there girlfriends broke up with them but since the habit of smoking during classes has caused them to drop out and not be able to meet new people and not able to graduate. Ive stopped before it got to that point. I was the only one that graduated. well didn't stop completely I would smoke rarely. Ive been 4 weeks clean from the rare time it would smoke a blunt every 2 to 3 months. They smoke everyday. I have found a job in this bad economy and now going into college. My friends found out about my job knowing that I wouldn't just give them money they would sell things to me. I bought a dirt bike for $100 with a 250cc, an xbox 360 for $75 with COD and two remotes, a black berry curve for $20. they would sell cheap to buy more weed. its hard not to say no to such a deal. I tried to advised them to stop but they say "we cant." "I feel less stress when I'm high." two other friends has been arrested for the possession. They say there is no bad effects in smoking weed but what I witnessed I find that hard to believe. Are you a former user of weed, and how have you felt since you stopped? even yet if you do smoke do you feel that its a problem?

Suggestion:

I smoke, i haven't got lazy. I haven't got depressed. I actually feel better when doing it. It doesn't kill brain cells, it just freezes, slowing them down, then they will go back to normal after the high. It isn't addictive. It doesn't cause cancer. Studies have found that people that smoke are just as normal as others that don't smoke. Everyone around me who smokes are perfectly normal, and healthy not lazy. I actually think it depends on the person, my other friends at school who do it were already lazy and they smoke so they just get fat. Remember it's the munchies.
