I did not know that psychoactive drugs were once used to address alcoholism.
Plus I did know know there was a drug that made you less high than you are naturally in your every day life without drug use
Ecstasy was perscibed to married couples who were haveing problems with their marriage . Speed given to soldiers in the world wars . Cocaine in bottles of coke , heroin for colds etc . Cannabis smoked by pregnant women for morning sickness. Before prohibition of drugs they were all regularly used in medicines .
Although one has to admit 19th century médecine was kinda sketchy. I wouldnt blindly follow the prescriptions they gave at the time.
Cannabis was also used to alleviate period pains - Queen Victoria was quite a fan, supposedly.
