Answer: 1960s
Many people began experimenting with drugs during the 1960s. During this decade, the number of Americans who had tried cannabis at least once increased over twentyfold. Between 1966 and 1968, the number of arrests for marijuana possession, had increased by 98%. The social and cultural movements that occurred during this decade are credited with the popularization of drug use among previously uninvolved demographics, such as people in suburbs and rural areas.
