I don't think it's likely that they would be imprisoned.
Under our current law, merely giving somebody a drug—you don't need to sell it to him—constitutes the offence of trafficking. Mr. Obama admitted that at one point he used cocaine. If he had been in Canada and he had been 18 and shared some cocaine with a friend who was 17, a minor, or if he had done this near a school, that would be a mandatory minimum sentence of two years' incarceration. That means federal penitentiary. That does not make sense to me. Look at the tremendous potential that we would have lost with this man. He has gone on to offer tremendous promise to the United States and many other countries as well. That could have been the consequence of his being subjected to a law like this. He wouldn't even properly be allowed into the country. He's a head of state so we allow him into the country, but because he admitted drug use in the past, we could turn him away at the border. This makes no sense whatsoever. This is a problem that could also have applied to Mr. Clinton or Mr. Bush.
This is how absurd our laws are. I look at my own class of capable, intelligent students. Of course, there are good and bad ones, but by and large I am pleased with them. Some of them could get caught up with this law.
