Albert HofmannLSD was my "wonder child", we had a positive reaction from everywhere in the world. Around two thousand publications about it appeared in scientific journals and everything was fine. Then, at the beginning of the 1960s, here in the United States, LSD became a drug of abuse. In a short time, this wave of popular use swept the country and it became "drug number one". It was then used without caution and people were not prepared and informed about its deep effects. Instead of a "wonder child", LSD suddenly became my "problem child".
