That is impossible and does not even pass a basic math.

317,493,212 is the current population. If you discard people under 15 and over 70 you are left with the you have (219685604) that means 20% of the US smoke pot.

Pot people always like to over inflate the usage number, but 14% too funny. Even in states where its legal, it would not reach 20%.

You'd be surprised.

(But to be more actual, it's probably those numbers are not for "smoke pot" but mostly for "have smoked pot at some point").

Btw -- you said "That is impossible and does not even pass a basic math", but you proved it neither impossible, nor that it does not pass some math test. Just that you find the number too big.

People under 15 and over 70 smoke pot.

According to this 38% of those surveyed and 17% of those over 65 admit to trying pot. http://www.gallup.com/poll/163835/tried-marijuana-little-cha... Though only 7% of those surveyed where willing to say they currently smoked.

As a sanity check if you where 15 in 1960 your ~69.

PS: Though, in an informal survey's my 14-15 year old classmates in the 1990's over 90% said they had used pot in the last year. So their numbers might be off.

Yeah sure but statistically it is not significant. There is a two year chinese kid that smokes 2 packs a day, but that does not mean a significant number of 2 year old kids smoke.

Also if 14% of people smoke pot that means 80% of all house household smoke pot and it is NOT true.

My point is it's a high variance statistic which is hard to control for.

If population A = 95%, Population B = 30%, and Population C = 1% then it becomes vary important to get the correct ratio of populations A, B, and C. And correctly sampling culturally diverse populations in the same geographic area is vary difficult. Something as simple as a phone screen is unlikely to work due to things like % of population in prison or number of phone numbers in a household. Even block by block analysis can fail with transient populations as it's easy to introduce bias by counting someone twice or not at all.

1 in 5 adults is "impossible"? By what logic? There is nothing remotely impossible about that.

I bet if I said that 14% of the US population drinks alcohol, you'd say it was way too low.

What about your "basic math" argument applies to pot but not alcohol?

[internet2pac]

I would not say that. But lets you are right. Do you know the infrastructure is involved in supporting 14% of people in the US drinking alcohol?

Pot smokers confuse... "I have one time tried smoking pot" with "14% of america consumes alcohol". It is not the same thing, but you use it as if it is. That is the lie... they knowingly or through lack of braincells from smoking pot get this point intentionally wrong.
