Weed is nice. I used to smoke a half oz a week, which involved smoking every night (for about ten years.) I wouldn't recommend it as a long term thing, because you eventually lose motivation for many things. I've cut down now(less than a Q a month,) and I'm far less lethargic than I used to be, better at work because my mind is sharper + I feel the effects more when I smoke now.
I have been smoking weed almost every day for about 28 years. I'm still healthy, horny, happy, I have a really good job a degree, professional certifications life is good. Just do it in moderation. Don't smoke 2 or three joints a day by yourself you'll turn into a veg head. Get a one hitter or bong and just smoke enough to get a good buzz and relax after work or on the weekends. If you smoke alot everyday you will become a lazy burnout after awhile. Try using it as a reward. Do project around your house or clean up a mess and reward yourself when your done. If you smoke the weed first your done man you will just eat a twinkie and sit on the couch.
