I read this study year or two ago that stated that short-term THC use (few weeks) did not have effect to neurogenesis in rats, but long-term THC use (few months) did have negative effect on neurogenesis. This negative effect on neurogenesis did not happen to rats that got both THC and CBD.
While I have heard that association between neurogenesis and depression has been questioned, I think this is very valuable thing to consider.
Could you link that study please? That sounds absolutely fascinating to me.
As I get older I’m noticing as my cannabis use increases so does my depression. I’ve been trying to cut back, somewhat successfully, but it’s really hard after 20yrs daily use.
