Brief Summary
This study will evaluate drug-drug interactions between cannabis extracts containing Tetrahydrocannabinol (THC) and THC+ Cannabinoids (CBD) and probe drugs for select CYP450 pathways including: caffeine (CYP1A2), omeprazole (CYP2C19), losartan (CYP2C9), dextromethorphan (CYP2D6), and midazolam (CYP3A).

Conditions
Outcome Measures
Primary Outcomes (6)
Losartan Area Under the Curve (AUC) in Plasma
Area under the curve concentration (h\*ng/mL) of losartan in plasma using data points obtained 0, 1, 2, 3, 4, 6, 8, 12, and 24 hours post-dose
24 hours
Peak Change From Baseline Number of Correct Trials on Paced Auditory Serial Addition Task (PASAT)
Computerized version of Paced Auditory Serial Addition Task will be administered to assess working memory performance. Reported data reflect the peak change from baseline in the total correct trials out of 90 recorded (lower scores indicate worse performance) obtained 1, 2, 3, 4, 6, or 8 hours post-dose.
8 hours
Peak Change From Baseline Cognitive Performance as Assessed by the Divided Attention Task
Cognitive performance will be evaluated with the Divided Attention Task. Reported data reflect the peak change from baseline performance measured as the mean distance (in computer pixels) of the mouse cursor from the central stimulus recorded 1, 2, 3, 4, 6, or 8 hours post-dose. Higher scores indicate worse performance.
8 hours
Drug Effect Questionnaire (DEQ) - Peak Score for Feel Drug Effect
The DEQ will be used to obtain subjective ratings of "feel drug effects". Score range from 0 (none) to 100 (extreme) using a 100mm line anchored with none/extreme designation. Peak rating within 24 hours post-dose is reported.
24 hours
Number of Correct Trials on the Digit Symbol Substitution Task (DSST)
Computerized version of Digit Symbol Substitution Task will be administered to assess psychomotor performance. Results reported reflect the peak change from baseline on the total correct trials in 90 seconds (lower scores indicate worse performance) assessed 1, 2, 3, 4, 6, or 8 hours post-dose.
8 hours
Peak Change From Baseline Beats Per Minute for Heart Rate (HR)
HR will be obtained using an automated monitor to evaluate changes in beats per minute as a function of conditions. Data reflect the peak change from baseline measured 1, 2, 3, 4, 6, or 8 hours post-dose.

Study Arms (3)
Inje Cocktail
ACTIVE COMPARATORSingle oral administration of caffeine (100mg), omeprazole (20mg), losartan (25mg), dextromethorphan (30mg), and midazolam (1mg)
Inje Cocktail + THC extract
EXPERIMENTALSingle oral administration of Inje Cocktail + brownie infused with cannabis extract containing 20mg THC
Inje Cocktail + THC/CBD extract
EXPERIMENTALSingle oral administration of Inje Cocktail + brownie infused with cannabis extract containing 20mg THC and 640mg CBD
Interventions

Eligibility Criteria
You may qualify if:
- Healthy adult between 18-50 years old
- BMI between 18 to 34 kg/m2
- Willing to use birth control
- Willing to abstain from all medications and citrus fruits for the duration of the study
You may not qualify if:
- Medical or psychiatric illness judged by the investigator to put the participant at greater risk of experiencing an adverse event due to drug exposure or completion of other study procedures.
- Use of medications which, in the opinion of the investigator or medical staff, will interfere with the study outcomes or the safety of the participant.
- Clinically significant impairment of kidney, liver, or thyroid function (serum creatinine \>1.2 mg/ml (kidney), liver function tests \>3x the upper limit of normal (alanine amino transferase \>99 U/L; aspartate amino transferase \> 99 U/L), and thyroid stimulating hormone \> 4.2 uIU/ml), or evidence of current anemia based on blood chemistry testing.
- History of adverse events associated with the ingestion of cannabis or any medications in the Inje cocktail judged by the investigator to present an undue risk of harm to the participant.
