Actually no it isn't just your business, especially if you are ingesting a substance that is not only illegal in Canada, but the legalization would make Canada in further in violation of a treaty the Liberals signed with the U.N. on illicit drugs. Having the safe injection site in Vancouver is already in violation of that treaty, and we have the same nutcases who are proponents of expanding it's use to include the provision of crack-cocaine pipes, and the allowability to smoke their crack in this place.
It is the Liberals and the NDP who always haul out the U.N card whenever they want to score some political points against the Conservatives, but it was the Liberals who signed the U.N. Treaty to fight the use of ALL illicit drugs, and marijuana is included as one of those illicit drugs. You can't have it both ways and allow those who don't want to obey the law to break it as they see fit just because they don't happen to like the law as it is written, and expect the rest of us to adhere to the laws the rest of us don't like. For instance I don't like the fact that the CRTC crams mediocre Canadian talent down our throats, I don't like being stopped by the police for speeding, and I especially don't like it that we arrest drunk drivers, while we allow people to operate a motor vehicle stoned on grass.
A society cannot pick and choose which laws they want to obey, because if we allow that we may just as well get rid of the laws, get rid of the police, dismiss the judiciary, close prisons, and just allow the country to go back to a "Wild West" scenario, where there was no law, and people could do pretty much as they pleased. As society developed it became necessary for all of the above to ensure the safety of society. Without is we will need to stay in our houses, and hope that nobody decides to break in and rob us. That is especially scary since the Liberals, NDP and the Bloc want all guns confiscated, and that will mean that the only people who will be armed will be the police, criminals, and the military. The military I'm not so sure of, because if you listen to the above mentioned political parties, they want our troops to go into hostile territory with a white flag, and do construction and humanitarian work, while hoping that the enemy doesn't decide to shoot.
