We conducted eight separate LSD-related surveys between October 2005 and January 2006, most of which collected responses for 3-7 days. Six of the eight surveys were "micro-surveys" consisting of 3-4 questions each, displayed at the top of nearly all pages on the Erowid.org website, ensuring a high response rate. Each micro-survey yielded between 3,000 and 6,000 responses per 24-hour period that it was displayed. The other two surveys were identical and longer, attempting to identify trends in current LSD availability. We received a total of 136,057 responses to the eight surveys; 123,459 of these (90.7%) were determined to be valid after the removal of spam, duplicates, and invalid responses.

An article describing the results of these surveys was published in Issue 10 of Erowid Extracts.
