About this study
The goal of this clinical trial is to learn if drug ABC works to treat severe asthma in adults. It will also learn about the safety of drug ABC. The main questions it aims to answer are: Will a marijuana-based drug help anxiety in autistic adults? Anxiety can make socializing and working more difficult for people. Researchers will compare a marijuana based drug (that is mostly CBD with a small amount of THC) to a placebo (a look-alike substance that contains no drug) to see if the drug makes symptoms of anxiety better. Participants will take the drug (or a placebo) every day for 8 weeks and keep a diary to record the time they took the drug, and their feelings each day. The drug is taken orally in drops once or twice a day. The study staff will speak to the participants weekly either over the phone or in the clinic. Clinic visits once every 2 weeks for checkups and tests. The researchers will make sure participants are healthy and see if there are any changes in anxiety.
