On the CBC news this morning there was a story about protecting your privacy when buying Cannabis from retailers. Using a credit card may impact travel plans. The best obvious option would be that retailers and online retailers accept Bitcoin to protect buyers privacy.
Canada is a known country which is friendly for cannabis users, but yeah, I don't think other countries would be too welcoming to Canadians who may have had taken their hits at the bong prior to visiting their own land. Idk how other countries would do the background checks specially on card transactions but I guess it's better to be safe than sorry.
Funny thing is if government run online retailers accept Bitcoin to sell cannabis, are they the new Silk Road?
If it's legal on their own country, why would it be the new Silk Road? Also, it would be highly improbable for the government to create their own retail of cannabis using bitcoin as they would be under hot water once other media outlets found out about this, but it's never impossible.
