Hey, I'll chime in on this. I get very strange and paranoid (anxiety) when I smoke high THC strains. I've suffer from anxiety and depression my entire life, often time sometime debilitating with panic attacks. I started using cannabis to help me with this and It's helped a huge amount. I can honestly say I'm a different, much improved person.
I grew Candida CD-1 for my first crop along with Jack Herrer. I will use the CD-1 in oil form or smoke and that works great by itself for depression and anxiety. Often I will add in a tiny amount of Jack Herrer when I smoke. Just a few grains of it from my weed grinder. I find this mixes with the CBD of the CD-1 and helps with my depression and anxiety. It give me a noticeable mood boost and calms my negative thoughts to the point of me not listening or reacting to them. It also slowly over time has helped me get used to THC in little amounts to where I notice the normal paranoia that I experience is not there nearly as much. If I do feel it I can have some mre CBD in some form and it will take away some of the THC effect and calm me down.
Now I can benefit from the THC/CBD mix without the associated paranoia/anxiety and I can truly relax and feel lifted. It;s helped me with my depression so greatly and social anxiety that I'm living a much fuller life.
Any CBD strain with less than 2% THC is what you want CBD as high as you can get, over 15%. Use the THC strain sparingly and always have the CBD backup if you start to feel bad, for balance. The tow working together in the right dose is key.
I find that straight Sativa strains are energetic and without the CBD can cause runaway thinking that develop into anxiety.
EDIT----HA, I see that I chimed in already above, long ago. I'll keep this here anyway because I think it's relevant and not redundant to what I said before. Growing a Dinafem Dinamed CBD+ right now.
