Oil often is CBD.
You might consider making it yourself.
There are youtube videos about that.
You could also buy flowers and bake it as per online instructions then stuff into empty gelatin capsules.
Another idea is to buy a dry herb vape where you're not combusting the weed. It is quite mild at lower temperatures up to 190 C.. Then you can use the vaped weed again in capsules.
Eating raw unheated flowers will do nothing.
