Ability and capacity to comply with the study and follow-up procedures 8. Subjects must be scheduled for surgery no less than 5 days from the planned start of day 1 and no more than 56 days from the planned start of day 1. 9. If patients are taking home regimens of CBD or marijuana, they must consent to abstain for the length of the trial. Exclusion Criteria: 1. Subjects undergoing neoadjuvant chemotherapy or neoadjuvant endocrine therapy 2. Subjects who are pregnant or are lactating. 3. Patients taking drugs metabolized by cytochrome p450 (warfarin, amiodarone, levothyroxine, clobazam, lamotrigine, valproate, prednisolone, hydrocortisone, clarithromycin, itraconazole, erythromycin, fluconazole, clopidogrel, rifampin, sulfamethoxazole, any opioids, antiepileptic medications (including carbamazapine, phenytoin, valproic acid, but excepting of gabapentin, clonazepam, or diazepam). 4. Routine use of recreational or medicinal marijuana products (defined as > 4 times per month) or illicit drug use including opioids, cocaine, amphetamines, PCP, LSD 5. Concurrent use of over-the-counter CBD oil, Marinol®, Delta-8 THC, or cannabis 6. History of allergic reactions attributed to compounds of similar chemical or biologic composition to CBD or placebo 7. Underlying history of epilepsy/ recurrent seizure disorder or unexplained seizure within past 6 months 8. Patients with uncontrolled cardiovascular disease defined by myocardial infarction, stroke, or transient ischemic attack, or need for coronary stent placement within past six months. 9. Patients with a psychiatric illness or psychiatric symptoms that would prevent them from completing study procedures or would disqualify them from surgical intervention (e.g., untreated schizophrenia, bipolar disorder, or suicide ideation/attempt resulting in psychiatric hospitalization within the last 30 days). 10. Women who are pregnant or breastfeeding or who refuse to practice an effective form of birth control (condoms, diaphragm, birth control pill, IUD)
