O.K., I have heard that the pure indica varieties are higher in CBN and lower in TCH, and that they are more effective on pain. It stands to reason that sativa dominant strains would be more mental and a better mood elevator.

Anyhoo, it has been my experience that the indica will diassociate you from pain. It does not really kill the pain but it removes you from it. That is what I have always used the wide leaf ganja for.

Sativa in the morning and indica in the evening...that is really all I know about it.

There are strains that are marketed as being targeting specific problems. I dont know what to think about that.
