At this time, Pebble does not claim to treat cancer or neurological disorders. The information provided on this site is for self-sufficient adult patients and caregivers. We have provided what the current valid research says about specific cannabinoid isolates and their potential with targeted indications. We have shared Pebble’s proprietary formula that combines those individually-researched cannabinoids with other proven plant-based anti-inflammatories in specific ratios, using guidelines on dosing and dose scheduling, in a focused effort to create a synergistic effect greater than the most beneficiary isolates. Please review in detail and make your own decision.

In-House Case Studies
Sponsored Ovarian Cancer Pre-Clinical
Pebble is sponsoring a partnership with MD Anderson Cancer Center to complete pre-clinical trials for treatment of ovarian cancer. The start dates for the first in vitro and in-vivo studies will be set once the social-distancing restrictions are lifted. Currently (as of June ’20), we expect to begin receiving reports on results in Sept/Oct. 2020.
The results from the first two phases of this collaboration will be utilized for both cancer and neurological-disorder drug development and procurement of non-dilutive funding by submitting a product development proposal to the Cancer Prevention and Research Institute of Texas (CPRIT).
Referrals & Rewards
Pebble’s growth depends on word of mouth from successful Pebble People. We need to gather as much data as possible.
Please refer anyone who is battling any of these these neurological disorders. Please also refer folks dealing with these cancers, taking these chemotherapy drugs, or experiencing any of these chemo side effects.
To show our gratitude, we’ll repeat your most recent order for free, no matter how big it was. Pebble will also automatically setup the person you refer (as an already diagnosed medical patient) with a permanent 40% off personal discount code.
