Here is the thing
You are likely to not notice the effects of CBD products in less you are really in tune with your body.
If you have a lot of pain you may notice immediate effects though...are you a sore person from an injury or working out? It may be good for immediate relief and reduced inflammation.
CBD and Cannabis overall can have long term/long game positive benefits....This is a developing field because little research was allowed to be done until recent years...I believe cannabis usage has long term benefits, and that is part of the reason it is the plant with the longest known relationship to Humans.
CBD works best if consumed with THC...this is fact, and absorption and effect increase with both in the system...I personally would not use products with zero THC, both are needed for health benefit(can be a very high CBD:THC ratio though)
