Stoners stick out like a sore thumb in the workplace. Management will know you're a stoner.
Sure they go to work and do ok, but noticably and consistently struggle with anything requiring inititive or critical thinking. A partern of mistakes, generally unimportant or minor mistakes, is generally a feature of their work.
Their social attitude varies from person to person, but under it almost always the guys are passive agressive and the girls are moody.
So yeah, you will get by at your 35k job, but you are probably going to be overlooked at promotion time.
