“Over the history of pharmacology there are numerous examples of drugs being widely distributed, almost ‘trendy’, prescribed by physicians in a certain period as a sort of panacea, and then neglected, forgotten, or even forbidden as they become considered dangerous in the light of clinical observations. One of these drugs is Cannabis, which was very popular in the 19th century until disappearing from the official Pharmacopoeia at the beginning of the 20th century and reviving again in the new millennium.”
