Is weed harmful for health?

There's a hangover that's more subtle than an alcohol hangover but it leaves you mentally foggy for a day or two afterwards, so if you smoke weed a lot, you're always a bit out of it. I never used it during the school year or when I was working because I had to be sharp and be able to get stuff done.

Inhaling combustion products is never going to be good for you, although even George Clinton probably doesn't smoke 20 joints a day like with cigarettes.

That said, if you're going to use drugs, then weed is by far the least harmful.
