I dreamt that I was close to some people doing research into sustainable use of drugs. Coming from a large university, they spanned many disciplines, but most of them were medical scientists. They were concerned with leading investors, brokers, and bankers rather than run-of-the-mill drug abusers. The research had to do with the dynamics of drug use, which often starts with marijuana and then moves on to more powerful drugs, such as cocaine or heroin. The main research question had to do with viable ways to return to marijuana or abandon all drugs later in life without serious consequences on health in general, including mental health. I do not remember much about the project, but I remember quite well that the whole research team was becoming rather despondent about their findings. Although not impossible, sustainable use of drugs was very difficult to achieve in a large enough number of subjects. Most investors, brokers, and bankers involved in the research had serious health problems later in life. Debilitating depression was very common among them, but this was only the tip of the iceberg. When I woke up in the middle of the night, I could not believe my dream. Knowing nothing about drugs, how did I become so close to the research team? It took me a while to fall asleep again, but the bewilderment remained till the morning.
