Dear Erowid Readers: We're a small nonprofit that runs the top drug information website in the world. We have only 4 staff but serve 12 million users, and have costs like any big website: servers, power, office space, programs, and staff. To protect our independence, we don't run ads or take government funds. If everyone reading this gave $3, our fundraising would be done today. If Erowid is useful to you, take a minute to keep it online and ad-free another year!

De Giacomo U. 
“Les catatonies toxiques expérimentales”. 
Acta neurol.. 1951;6:5.
300-500 mcg. LSD caused in 5 of 12 mental patients an initial phase of excitation followed by catatonia-like symptoms with stupor and catalepsy, resembling that noted after the administration of bulbocapnine. In low dosage, LSD causes mental excitation, but in high dosage hallucinatory mental confusion and catatonia.
