"that a combination of 10 mg of THC-A and less than 1 mg of CBD-A will be a better treatment for pain and less of a high. We like the sound of that. Is it okay for a 1st time user?"
This would be okay for a first timer if you are not heating these up. THC-A is THC that has not undergone a chemical change to become a psychoactive compound. As a result, it will not cause you to feel "high." If it is heated it will become THC and cause a high. The CBD will not cause an intrusive psychoactive effect regardless of the temperature.
