"I don’t understand how the balms and patches work for pain"
Transdermal cannabis products (such as patches) are formulated with specific carrier substances that allow its cannabinoids to penetrate the bloodstream, giving you global relief rather than a localized effect.
The THC in most topicals is not designed to reach the bloodstream and give you a psychoactive effect. Instead, THC-rich topicals are preferred for treating acute pain from bangs and bruises, whereas CBD-leaning topicals target pain due to inflammation.
