Every year , on April 19 , an authoritative anniversary rolls around that you may never have get wind of . To those in the know , it ’s called Bicycle Day , and it commemorates the first - ever intentionalLSDtrip .

It all started when a Swiss chemist called Albert Hofmann had a very peculiar metre while cycling home from the lab . Hofmann was the first soul to synthesize LSD back in 1938 . He did it by isolating chemical compound find in a fungus called Claviceps purpurea , which infects grasses like rye and can have someprofound effectson any man unfortunate enough toaccidentally consume it .

It ’s safe to say that Hofmann did n’t think much of his breakthrough to begin with . What we now sleep with asLSDwas actually the 25thin a long line of standardised compounds that he ’d been experimenting with , and Hofmann ’s research notes from the timereportedly revealhow no one was specially enthused by it : “ The new center , however , aroused no special interest in our pharmacologists and physicians ; examination was therefore discontinue . ”

Five long time later , though , in 1943 , Hofmann turned his aid back to LSD . As the account goes , he was intrigue by the strange sensations he had palpate when he had accidentally absorbed some of the compound through his skin , so much so that a few day later on he decided to take some deliberately . It was only 0.25 milligrams , but it was more than enough .

It was n’t long before thesensationsbrought on by the drug began to overwhelm Hofmann and he decided to head home . Unfortunately , since this was during the Second World War , the only agency of transport available was a bike , and the journey was about 4 kilometers ( 2.5 miles ) . So began the first - ever window pane trip – in both grass of the word .

“ I had to struggle to speak clearly . I demand my laboratory assistant , who was informed of the self - experimentation , to see me abode [ … ] On the direction home , my condition began to assume threaten forms . Everything in my field of vision wavered and was distorted as if seen in a curved mirror , ” write Hofmann , describing his experiences decennium later in his autobiographyLSD : My Problem Child . “ I also had the whizz of being ineffective to move from the spot . Nevertheless , my assistant later told me that we had travel very quickly . "

The delusion only grow stronger when he arrive home . “ Everything in the room spun around , and the conversant physical object and pieces of piece of furniture simulate grotesque , threaten forms . They were in continuous motion , animated , as if driven by an inner restlessness . ”

In the midst of his misstep , Hofmann was visited by a neighbor convey him Milk River , which he had specifically requested and chugged with abandon , despite the fact that said neighbour appeared to him as a “ malefic , pernicious witch with a coloured mask . ”

The remainder of the trip is described vividly in the book , including a visit by the crime syndicate doctor . It all sounds quite unsettling – but in his own countersign , Hofmann awoke the next morning feel jolly darn great : “ The cosmos was as if fresh create . All my senses vibrated in a condition of highest sensitivity , which persist for the intact day . ”

Hofmann continued his research into LSD , and afterward other psychedelics likepsilocybin . He trust that hallucinogenic drug could be of welfare to patients with psychiatrical disorders like schizophrenia , a view he maintain even when widespread amateur use of these drug in the sixties led to pushback from some quarter andeventual prohibitionin law .

“ I believe that if people would instruct to utilise LSD ’s vision - inducing capability more sagely , under desirable status , in medical practice and in coincidence with speculation , then in the future this trouble child could become a wonder child , ” he write .

Hofmann die in 2008 at theage of 102 . Nowadays , more and more researchers are get a fresh look at the potential medicative benefits ofpsychedelic drugs , and there have even beenmoves toward decriminalizationin some region . We can only guess that Hofmann would have been proud of to see his discovery becoming a topic ofserious scientific researchonce again .

Of course , we can continue to mark our calendars each April 19thas the day of remembrance of a truly round - delic event that changed the humans perpetually .
