E-cig issue

Hey folks

First off, this is my first time using a forum like this so I apologise in advance. This question may have been asked before but i have been scouring the web for 2 months with no concrete results.
I basically want a link to somewhere that i can buy good cannabis oil for my vape pen, preferably something that doesnt have to come from the US but if thats all there is I'll take it.
If this has been asked before if people could be kind enough to point me in the right direction I'd appreciate it muchly.
Thanks in advance

ive googled it back when i smoked ecigs theres tons of recipes. youtube marijuana ejuice theyll give ya the run down
