Is marijuana really bad for me?

I'm thinking of this...is it really bad for me? need to search on this...someone say it is not bad...

"Marijuana is the safest drug out there including prescription. There is not a recorded death in history caused from marijuana.I just wanna get high and be happy. You see marijuana hasn't wrecked my life but this wrongful charge has. Marijuana, in its natural state is the most therapeutic medicines known to man. I know this, thousands of doctors know this and even many politicians know this, but it is still illegal."
