I know people whose use of cannabis has been a crutch for problems in their lives, who have achieved less than they likely would have because it is so easy to do nothing, and stagnate, when drugs come easy. I also know people whose cannabis use has (unproveably, but likely) triggered latent schizophrenia. There are tradeoffs in everything, of course, and everyone is entitled to their own choices and ambitions, and these risks don't harm everyone who tries them, but put yourself in the shoes of the friends and family that see their loved one become a burnout. There can be real and justified hate of the drug when it has measurably damaged your family. There was an episode of South Park that addressed pot in a similar way- it is dangerous because it is so much fun you don't want to do anything else.
