Major constituents of cannabis: THC = Δ9-tetrahydrocannabinol CBD = cannabidiol THC = main psychoactive ingredient of
cannabis. It also has orexigenic (having a stimulating effect on appetite), analgesic, and antiemetic effects.
CBD has no psychoactivity, it primarily reduces pain and inflammation, and do many other things.

“What medications contain cannabinoids?
Two FDA-approved drugs, dronabinol and nabilone, contain THC. They treat nausea caused by chemotherapy and increase appetite in patients with extreme weight loss caused by AIDS.

The United Kingdom, Canada, and several European countries
have approved nabiximols (Sativex®), a mouth spray containing THC and CBD. It treats muscle control problems caused by MS. The United States is conducting clinical trials for its safe use in treating cancer pain.Although it has not yet undergone clinical trials, scientists
have recently created Epidiolex, a CBD-based liquid drug to treat certain forms of childhood epilepsy”.

My literature research focuses on the effect of cannabis on human bone from studies of over five years for a large control group of people
who do not smoke or use any form of cannabis beginning to smoke marijuana and receiving prosthetic implants include dental implants on this same group of people.

I can not find studies of cannabis on human bone.
Cannabis has only been given to rats and in vitro experiments in my literature researches.

Increase of mesenchymal stem cell migration by cannabidiol via activation of p42/44 MAPK(mitogen-activated protein kinase).By Schmuhl E1, Ramer R2, Salamon A3, Peters K3, Hinz B4. PubMed-Biochem Pharmacol. Epub 2013 Dec 1.
“Collectively, this study demonstrates CBD to promote the migration of MSCs via activation of the CB₂ receptor and inhibition of GPR55 and to induce osteoblastic differentiation. CBD may therefore recruit MSCs to sites of calcifying tissue regeneration and subsequently support bone regeneration via an osteoanabolic action on MSCs.”

Effect of cannabidiol on human gingival fibroblast extracellular matrix metabolism: MMP production and activity, and production of fibronectin and transforming growth factor βBy S. Y. Rawal1,2, M. Kh. Dabbous1,3,4,5 and D. A. Tipton1,3 first published online: 17 NOV 2011-Journal of Periodontal Research Volume 47, Issue 3, pages 320–329, June 2012
“The data suggest that the CBD may promote fibrotic gingival enlargement by increasing gingival fibroblast production of transforming growth factor β and fibronectin, while decreasing MMP production and activity.”

Patient is happy with the result of healing from his first implant in # 8.
He is motivated to be in the study and to have five more implants in teeth #s 20, 21, 28, 29, 30.
Bone around #8 heals very well More studies on human with longer oberservation should be done for strong support of Cannabidiol usage in bone healing and or bone loss.
