but the effects you describe only occur after very frequent use over a longer period of time. Most of my friends like to smoke, some of them on a daily basis, but they seem to do just fine on a productive level. Lazy people will find reasons to be lazy. If you don't want to do shit all day, smoking weed is a very easy way to kill time, but it's not gonna make you quit your job.
