The best CBD strains have 20 to 1 CBD to THC. Most CBD strains have 10 to 1. Research suggests that this low level of THC is beneficial even though it does not create any high. Research also suggest that the medicinal value of THC is at lower levels, not the higher levels.

As I stated previously, THC vaporizes at a lower temp than CBD so any THC effect will appear first if you are vaping oil or dried plant.

I don't think any of us should be smoking it. There are too many toxins in smoked marijuana whether it is high CBD or not.
