There were never any laws in the first place
All the ecigs in gas stations/corner stores/etc are non-nicotine. Still though, we have a ton of great juice vendors in Canada and it's not an issue getting nic juice from US vendors, either
I will second Canvape. They have an awesome selection of products and the best prices you will find. I really really like their 306LR atty. They have quite a few different styles of drip tips as well, not so much for the 306, but for anything 510 they have quite the selection. Keep an eye on their coming soon section, too. They just moved and are expanding, with a ton of new and awesome stuff on order. Soon as they're settled again that coming soon section is gonna BLOW UP!!
Can't wait
I would also highly suggest the Firebird 3ml bottom coil tank from Canvape. They're the only Canadian vendor and this product has been raved about in the States. Happy to say after about 2+weeks with mine that it's fantastic. Haven't gotten a single leak, or a single dry hit (And I vape this bad boy right down to the last drop!). Awesome flavour and vapour. A great battery I would suggest for you is the Ego Twist. It's about $25 and Variable Voltage (this is all the craze nowadays, once you go VV you won't go back, it allows you to change the voltage from 3v-6v by just twisting the bottom. This way you can find that perfect sweet spot for all the different cartos/attys/juices that you have. It's awesome, I have quite a few mods but I find myself using the Ego Twist a TON!
I'm so excited for you! It's a world of new wonders out there!
