This study is designed to help doctors understand how to safely - and at what dose – to give the study drug to patients suffering from acute kidney injury with accompanying acute hypoxic respiratory failure (AHRF). The study is testing Auxora (study drug) against placebo (a substance that has no medical effect).

Your chance of receiving a dose is 50% (for every 1 who receives placebo, 1 receives a dose of Auxora). This selection process is called randomization (like a ‘flip of a coin') and neither you nor your study doctor will know to which group you have been assigned. Every patient in the study will receive his/her dose of Auxora or placebo once a day, for 5 days in a row.

This study will examine genetic factors that contribute to the different ways people feel after consuming cannabis. People that use cannabis at least 4 days per week will participate in a study involving 1 in-person visit followed by a 5-day remote assessment period. The in-person visit will determine if an individual is eligible for study participation and their blood will be drawn to assess genetics. During the remote assessment period, participants will complete multiple short surveys per day describing their feelings and their recent cannabis use.

The purpose of this research study is to investigate whether combining transcutaneous auricular vagus nerve stimulation (taVNS) with computerized cognitive training might help improve thinking abilities and mood. Participants will self-administer these two treatments in their homes (two 1-hour session/day for 10 days). They will undergo pre- and post-treatment assessments of thinking abilities and mood and a brain MRI.
