Study type | Interventional |
The goal of the proposed, proof-of-concept study is to test the combined effects of vaporized marijuana [Delta-9-tetrahydracannabinol (THC)] with NLX as a proof of concept towards the possible development of a combined overdose reversal agent with improved tolerability.

Current or history of a psychiatric condition that would affect participants' ability to provide informed consent (e.g., mood disorder with functional impairment or schizophrenia) or make participant hazardous for the participant (e.g., recent suicidal ideation) or staff (e.g., significant history of violence). 3. Current DSM-V diagnosis of substance use disorders requiring medically managed detoxification, other than OUD (e.g., alcohol or benzodiazepine dependence). 4. Medical condition resulting in chronic pain (>3 months). 5. Clinically significant abnormality on physical examination, vital signs, screening laboratory tests, or 12- lead ECG. 6. Significant cardiovascular, hepatic, renal, respiratory, gastrointestinal, endocrine, immunologic, dermatologic, hematologic, or neurologic disorder. 7. Any surgical, or medical condition that may interfere with the absorption, distribution, metabolism, or excretion of the study drugs. 8. Baseline hypotension, orthostatic hypotension or syncope, hypertension (blood pressure > 140/90), pulmonary hypertension or heart disease. 9. Any of the following values for laboratory tests: 1. positive pregnancy test, 2. hemoglobin < 12 g/dL in males and < 11 g/dL in females, 3. neutrophil count < 1.0 × 109/L, 4. platelet count < 75 × 109/L, 5. creatinine clearance < 50 ml/min per modified Cockcroft-Gault equation, 6. aspartate aminotransferase or alanine aminotransferase > 3.0 × upper limit of normal. 10. Hypersensitivity to opioids, history of significant adverse reactions to cannabinoids, and allergy or contraindication to any other drugs administered as a part of this investigation. 11. Use of an investigational agent within 30 days. |

Primary | Clinical Opiate Withdrawal Scale (COWS) | Clinical Opiate Withdrawal Scale is an 11-item, clinician-administered measure designed to quantify the severity of opioid withdrawal. The COWS evaluates the severity of the following symptoms on a scale of 0-4 or 5: resting pulse rate, sweating, restlessness, pupil size, bone or joint aches, runny nose or tearing, gastrointestinal upset, tremor, yawning, anxiety, or irritability, and gooseflesh. The score on the COWS ranges from 0 to 48 points with withdrawal ratings between 5-12 considered mild, 13-24 as moderate, 25-36 as moderately severe, and >36 considered severe. | 4-weeks trial |
