Doesn't work as a mood enhancer for me- I'm still a reet miserable coont
No sides that I'm aware of and no addictive qualities although there is apparently a risk that you can become reliant on its effects so not exactly an addiction as such (probably similar to gear?) so I only use it when required.
I got mine from my local vape shop, is 1000mg dosed and is premixed with PG and VG (types of glycol) which means you don't have to add anything to it if vaping. It is Hope brand CBD oil, made in Scotland so hopefully trustworthy. A bottle and a slimline vape device came to £65.
