LSD was created to help people overcome mental illnesses back in the 1930's. So your correct, it can and did help many to overcome their illnesses but later better medications were developed that helped even more, so they say. To be able to see sound, watch walls become moving murals of brilliant , electric colors ever changing and reforming into new designs and textures was a sight I'll never forget. The sights I saw on my trips remind me allot of fractals today, do you see that as well?
