I have been taking 1 dropper full of Hempworx 500mg oil tincture ($80). If I take more than that I do risk increasing my anxiety due to THC content and to offset this I take 3 – 4 droppers full of Green Horizen 500 mg oil tincture ($100, I think) 100% THC free. Note, these brands are very over priced so I am looking for other brands to try. Any suggestions? Leave them below.
