You should look into tinctures and/or edibles. Smoking cannabis has a 4-6 hour bioavailability while ingesting cannabis or CBD products provides longer relief. Also, cannabis based topicals also provide relief as well.
We find a lot of our customers come to us with lower back pain and they particularly like two of our CBD products: Rescue Balm: a CBD topical for targeted spots, we recommend using it before bed and rubbing it in very well. Our multi-use tincture Respira can be used as a vape and some people appreciate being able to use Respira throughout the day.
