They're downplaying them possibly because you can't die from marijuana withdrawal. It's physically impossible, you can experience nasty side effects but you will live. Compare that to a heroin addict, pain pill, or alcoholic who has a high chance of literally dying if they stop cold turkey.

Talk to those with withdrawal symptoms from "real" problem drugs and it won't even sound like the same experience. The other side is too, you're approaching this pretty unscientifically. It's possible you actually ARE depressed and aren't use to feeling it full force because you were self medicating for years.
