Hands down, one of the largest epidemics of pre-Doomsday were illegal drugs. In fact, most terrorist organizions and rebel groups usually funded their operations by selling and growing drugs. Doomsday, however, was an unexpected cure for this cancerous growth on society, as most people were more concerned with food than getting high. Following the collapse, many of the more complicated drugs to make, such as cocaine and MDMA were lost to the past. However, as society is slowly becoming less survivalistic, the trade is beginning to pick up in certain areas of the globe, along with new drugs surfacing.
