• A desire to reduce or stop drinking.
• Stable housing in the 3 months prior to screening with no foreseeable risk to lose this in the 3 months after screening,
• Agree to abstain from new/additional psychotropic medications, except for benzodiazepines as rescue medication prescribed by the PI or a stable dose of psychotropic medications in the 14 days (or 5 half-lives; whichever is longer) prior to enrollment/randomization with the intention to continue this medication during the study.

• Subject has a substance use disorder at time of screening (except for alcohol use in AUD subjects and nicotine use disorders),
• Subjects with cannabis or other drug use for at least 5 half-lives prior to screening, including nicotine use (i.e., subjects must abstain from nicotine use for at least five half-lives prior to screening).
• Subjects with symptoms of alcohol withdrawal or intoxication at time of screening (assessed using CIWA-Ar tool). if medically appropriate, intoxicated individuals will be provided transportation home while those experiencing alcohol withdrawal will be referred to an appropriate level of care.
• Subjects with history of seizures or epilepsy,

• Clinically significant abnormal vital signs (e.g., systolic blood pressure ≥139 mmHg, diastolic blood pressure ≥90 mmHg, heart rate \>90 beats per minute) at separate three measures before dosing,
• Clinically significant abnormal ECG parameters, including subjects with QTc greater than 450 msec.
• Clinically significant abnormal liver functions (ALT and AST), higher than three times the upper normal amount, clinically significant abnormal Hb, and/or clinically significant laboratory abnormalities (e.g., abnormal renal function, electrolyte derangements, etc.)
• Subjects who take, or are planning to take, any prescription or non-prescription medications, within at least 14 days (or 5 half-lives; whichever is longer) prior to enrollment/randomization, and for the entire duration of the study including: antipsychotic and mood stabilizing medications (including SSRIs such as Fluoxetine and Paroxetine, SNRIs and trazodone), OCT1 and OCT2 substrates (such as Metformin, Cisplatin, Imatinib, Procainamide, Citalopram, Cimetidine, Quinidine), monoamine oxidase inhibitors (MAOIs), tricyclic antidepressants (TCAs) or lithium, serotonin-acting herbal medicines and supplements, dietary supplements (such as 5-hydroxy-trypthophan or St. John Wort), and enzyme altering agents (such as and/or grapefruit juice and/or rifampin, barbiturates, phenothiazines, cimetidine, etc.) or any other medications that may have significant interaction with the study medication,
• Received an experimental drug or used an experimental medical device within 1 month or within a period \<5 times the drug's half-life for small molecules, or 3 months for biologics, whichever is longer, before the study drug is administered for the first time,
• Donated blood within 90 days or plasma within 30 days of study dosing,
• Any subject who may not be able to fulfill the study requirements per the investigator's clinical judgement. Additional Criteria for Healthy Subjects • Subject is unable to abstain from ingesting alcohol for 72 hours prior to dosing.
