The US is unlikely to refuse you entry based on this experience with Canadian customs; but if you want to again answer such questions in such a way as to land yourself into further trouble when attempting to get cleared for entry into a country, then who knows. And if you are in possession of contraband or perceived to be under the influence of contraband, then you're complicating matters for yourself more than necessary. [Of course the illegal use of cocaine is what complicates matters way more than necessary. ]

Yes -- a significant proportion of currency has some traces of cocaine and other hard drugs on it -- for example, the overwhelming majority of larger denomination euro notes in Spain and Italy have traces of such drugs on them.

[Note: You didn't spell "note" correctly".]

I recall reading somewhere that 4/5 (80%!) of the U.S. paper currency in circulation is contaminated with cocaine at a level detectable by drug-sniffing dogs.


Apparently, ATMs and automatic ticketing/vending machines account for most of the problem. Somebody snorts coke through a bill, then sticks the bill into a machine. Now, all of the bills passing through for weeks will be contaminated.

There are also trace amounts of rodent fecal matter/bug carcasses in processed foods and pharmaceutical drugs. I don't get people's obsessions with X containing trace amounts of Y. It's the larger amounts that matter.

They found traces of coke on your laptop?

Dude, keep doing coke if that's your personal choice, but buy yourself a mirror.

Or a nice glass coffee table...

or convert it to crack and get a lightbulb!

Per Snopes, it's true -http://www.snopes.com/business/money/cocaine.asp
(and I believe everything I read)

Short of forcing passengers to submit to a blood, urine or other bodily fluids test or other medical-type or lab examination, how in the world do you suggest that Customs go on to determine someone is under the influence of the controlled substance from passengers' use of such a substance a week or two weeks ago but not since?

Singapore used to clip a little hair off returning residents' heads if they had been in suspicious places such as Holland. (I don't think they do this any more).

To the op
Don't do coke it's bad for you.

This is technically true for customs, but not for immigration officers, and the systems they use are likely linked. If the immigration officer believes that you are attempting to enter the country for the purpose of breaking the law they can refuse you entry. If they think the OP is a coke dealer - even with no product on him - they can reject his entry since he is not a US citizen.

[QUOTE=stockmanjr;10053241]it's still none of their business.

For sure this is something that Canadian customs will record; you have admitted that you have broken laws, and show intent to do so in the future. With the current Canadian and American governments, I'd bet this would be something that CBSA shares with CBP. You gave the wrong answer, and stop with the coke!

Canada immigration can refuse Americans entry for some offenses committed, so likewise American immigration can likewise do the same to Canadians attempting to enter for whatever reason.

Like other posters said, you should have not admitted to anything.

With other trips outside of canada already planned, you'll likely be able to answer your own question(s) soon enough.

Do let us know what happens during or after your next excursion trip outside of Canada, especially if it's back to the US for whatever reason.
