The main purposes of this study are to (1) measure the effect of CBD/CBD-A on pain symptoms, pain intensity, pain unpleasantness, and skin sensitivity to hot and cold temperatures; and (2) measure the effect of CBD on brain electrical activity with electroencephalography (EEG).

Inclusion Criteria:

1. Men or Women;
2. 18-64 years of age with an incomplete or complete acquired traumatic SCI;
3. Must have experienced neuropathic pain for a minimum of three months before entering the study (neuropathic pain will be assessed using the International SCI Pain Classification);
4. The pain intensity must be in the moderate to severe category, which will be defined as a score of at least four on an NRS (range of 0 to 10).
5. Must have previous experience with consuming cannabis and or cannabinoids.

Exclusion Criteria:

1. Current drug (DAST-10: >6) or alcohol abuse (AUDIT: >10);

5. Adults who are unable to consent, women who are pregnant, breastfeeding, or not practicing an effective form of birth control (condoms, diaphragm, birth control pill, IUD), and prisoners;
6. Current pregnancy. Pregnancy will be evaluated using a pregnancy test during the first study visit. Female subjects of childbearing potential will be required to use two forms of effective birth control for the 3 months prior to participating in the study and continuing for 1 month after completion of the study;
7. Have a history of renal or hepatic disease: or
8. Have elevated serum creatinine above the laboratory upper limit of normal (ULN): or
9. Have elevated serum transaminases (ALT or AST) above the ULN: or
10. Have elevated total bilirubin above the ULN; or
11. Take valproate, due increased risk of liver enzyme elevation; or
12. Currently using strong CYP2C19 and CYP3A4 inducers; or
13. Have suicidal ideation (subjects should be screened for suicidal ideation); or
14. Cannot abstain from the use of alcohol during the study period, due to increased risk of sedation; or
15. Have a known or suspected hypersensitivity to cannabidiol or tetrahydrocannabinol.
16. Have a known or suspected hypersensitivity to sesame seed oil, lecithin, or bovine gelatin.
