How can it be more beneficial to use drugs then harmful?

How do people know what percentage of Americans use drugs?

• I heard Bill O'Reilly say today that drug use in America has fallen. How can anyone know this? I mean, I've never heard of or seen a survey done across the nation asking people what drugs they do. The very social stigma of drug use makes people keep their habits secretive. It seems to me, anyone who says drug use is up or down or anything of the sort is obviously lying because its impossible to know the numbers. Even the national food and drug administraion, ATF, CIA, FBI, anyone! They don't and can't know! So why do people listen to these people and believe them? "Marijuana use among teens is down %10 from three years ago" WTF? How could anyone possibly know that?

• Answer:

  From what I've seen, working in Healthcare and all the nurses and doctors that have raided stashes in nursing homes and offices . . . . . there is ALOT of drug use in this country. Don't be surprised if the majority of your neighbors, doctors, nurses, policemen, teachers, etc smoke weed recreationally.
