Bicycle Day is an annual celebration, falling on April 19th, that honors the first ever intentional LSD experience. This maiden trip was undertaken by the man who discovered it — Swiss chemist Albert Hofmann. This fateful day in 1943 soon kick-started a fascinating field of research, as well as a societal and cultural exploration, that continues to this day.

Kes oli Albert Hofmann?
Albert Hofmann oli Šveitsi keemik, kes on kõige paremini tuntud kui lüserghappe dietüülamiidi "isa", mille ise on kõige paremini tuntud kui LSD. Ta viis läbi teedrajavaid töid LSD ja teiste psühhedeelikumite omaduste kohta, nagu näiteks psilotsübiin maagilistest seentest. Tema teadustöö edendas inimese teadvuse mõistmist ja mõjutas neuroteaduse, farmakoloogia ja psühholoogia valdkondi. See oli ka katalüsaatoriks ülemaailmsele huvile psühhedeelikumite vastu.

Mis on LSD?
Lysergic acid diethylamide, is a psychedelic substance synthesized from a fungus called tungalteravik. It is renowned for its ability to cause profound changes in perception, thought patterns, and mood. It is categorized as a hallucinogen due to the trippy visual effects it can induce. However, these effects can vary based on dosage, setting, and the individual user.
Mis asi on siis ergotiga?
Ergot is a type of fungus that grows on grains such as rye. Its effects, both medicinal and toxic, have been registreeritud läbi ajaloo. Ergot alkaloids harbor potent psychoactive and vasoconstrictive properties, which is the reason that the fungus has been both utilized and feared since time immemorial. These compounds occur naturally within the fungus.
It’s first recorded use is from the Middle Ages, but there are numerous hints of its use in earlier history, such as the suggestion that ergot was part of the secret psychoactive concoction kykeon et vanad kreeklased jõid ajal Eleusinuse müsteeriumid. However, more often than not, ergot was accidentally ingested, as it grew on grains used to make bread — a staple food throughout much of human history. This could cause symptoms ranging from nausea, to gangrene, to death.
Albert Hofmann was busy studying the medicinal potential of these ergot alkaloids when he first synthesized LSD in 1938. He had been tasked by Sandoz Laboratories in Switzerland to develop a stimulant for respiration and circulation. Although on first discovery LSD was not considered significant, Hofmann had a funny feeling that there was something special about the compound, which encouraged him to return to the substance in 1943. This led to the now-celebrated events of Bicycle Day.

Millised on LSD mõjud?
LSD users report experiencing changes in their perception of time, space, and logic, as well as visual and auditory hallucinations. They also experience heightened emotional sensitivity, euphoria, and introspection, sometimes leading to spiritual revelation. The effects of LSD, or the ‘trip’, can last from 6 to 12 hours, depending on various factors, such as dosage.
LSD became synonymous with the counterculture movement of the 1960s and 1970s, its reach extending to music, fashion, art, as well as political and societal change. After being outlawed for many years, research into its benefits is back on track with studies showing that it has the potential to treat a wide-range of mental health conditions. These include depression, PTSD and anxiety.
Miks "Jalgrattapäev"?
So, why Bicycle Day? Why not ‘LSD Day’?
Well, with LSD up until pretty recently being designated ‘dangerous’, not to mention illegal by the powers-that-be, that title probably wouldn’t have flown. So, to get past the censors, Bicycle Day cleverly refers to Hofmann’s iconic bike ride he took after ingesting LSD on April 19th, 1943. It started off as a bit of a codename — if you tea siis sa tea 😉. Seda ei tohi segi ajada ülemaailmse jalgrattapäevaga, mis langeb igal aastal 3. juunil.
But what was so special about this infamous bike ride?
So, on April 19th, 1943 Hofmann decided to ingest 250 micrograms of LSD, having accidentally felt the effects while fiddling about with the substance a few days earlier. April 19th is observed, rather than the date a few days earlier (16. aprill), kuna see oli esimene kord, kui LSD võeti a meelega.
Pärast LSD manustamist (and not yet knowing that 250 micrograms is a very high dose!) Hofmann began to feel the effects quickly — within 40 minutes. Thus began an unprecedented psychedelic journey. The great Albert Hofmann was first to feel the profound effects of LSD that would change the world forever.

Later, Hofmann would describe experiencing extreme visual distortions, intense colors, and high levels of anxiety. By this point, he knew he had to return home as soon as possible. However, as it was still wartime, no cars were allowed on the road, so the humble bicycle was his only option. Accompanied by his lab assistant, Hofmann hopped onto his bike, and Bicycle Day began!
Hofmanni reis
Kogu sõidu jooksul koges Hofmann tugevat psühhedeelset mõju. Tema maailmataju oli märkimisväärselt muutunud, nagu oleks tema teadvus olnud kehast eraldatud. Ta teatas, et tundis end nagu maast kõrgemal hõljudes. Kõik, mida ta nägi, oli muutuv, värvid ja kujundid liikusid ja värelesid tema ees.
Despite this sensorial overload, Hofmann managed to get home, encouraged by the simple familiarity of riding his bike. The journey took around two hours, and once home, Hofmann sought help from a doctor. Being the patient zero of LSD, he could have no idea whether what he was feeling was a threat to his life, or just a hallucination. After being reassured that his vitals were normal (peale laienenud pupillide ja tema ilmse segaduse) he was able to relax, and lean in, to what he was experiencing.

As the effects of the drug wore off, Hofmann began to realize LSD’s potential as a tool to explore consciousness and enhance the human experience. He felt a deep sense of connection to the world, and a profound gratitude and appreciation for his existence. He believed this wonder could be used for great things. In an interview by Marlene Dobkin de Rios in 1996 Hofmann explained;
"Läbi oma LSD-kogemuse ja uue pildi reaalsusest sain teadlikuks looduse imestusest, looduse suursugususest ning looma- ja taimeriigist. Ma muutusin väga tundlikuks selle suhtes, mis saab kõigest sellest ja kõigist meist."
Hofmanni julge uurimisretk tundmatusse kuulub nende teadlaste ja uurijate suurde suguvõsasse, kes eksperimenteerivad iseenda peal. Tema kogemused panid aluse uuele uurimisajastule, mis mõjutas kõiki kultuurivaldkondi.
Millal tähistati esimest korda jalgrattapäeva?
Jalgrattapäeva algatas 1985. aastal Põhja-Illinoisi ülikooli professor dr Thomas B. Roberts. Alustades rohujuuretasandi üritusena, on selle populaarsus aastate jooksul kasvanud. Sellest on saanud varjupaik, kuhu koguneb suur hulk inimesi, kes on huvitatud psühhedeelistest ainetest, vaimu uurimisest, uimastipoliitika reformist ja muust. Tänapäeval toimuvad pidustused üle kogu maailma.
Kuidas saab jalgrattapäeva tähistada?
The Definitive Guide to Celebrating Bicycle Day 2025
Jalgrattapäev on aeg tähistada Albert Hofmanni pärandit, aga ka LSD ja psühhedeelikumite rikkalikku ajalugu ja põnevat tulevikku üldiselt. See võib toimuda mitmes vormis - alates pidudel osalemisest kuni psühhedeelikumite ajaloo tundmaõppimiseni. Siin on teile mõned ideed!

Osalege jalgrattapäeva üritusel
Otsige jalgrattapäeva üritusi oma piirkonnas. Paljud linnad ja kogukonnad korraldavad neid ning need võivad ulatuda grupirattasõitudest, paneeldiskussioonidest, kõnelustest, kunstiinstallatsioonidest või näitustest kuni filmilinastusteni. Nendel üritustel osalemine annab teile võimaluse kohtuda sarnaselt psühhedeelselt mõtlevate inimeste kogukonnaga. Samuti tõstab see laiemat teadlikkust sellest, et psühhedeelsed ained on paljude inimeste jaoks kasvav huvivaldkond ja et on oluline jätkata nende uurimistööd.
Viska oma jalgrattapäeva üritus
Koguge sõbrad kokku ja korraldage oma väike jalgrattapäeva tähistamiseks oma väike šin-dig. Võiksite vaadata psühhedeelset filmi või dokumentaalfilmi LSD või maagiliste seente ajaloost. Võiksite korraldada väikese tantsupeo klassikalise psühhedeelse muusika saatel. Veenduge, et kaasate mõne originaalse Woodstock rivistus oma esitusloendis!
Go on a Bike Ride and/or Have a Picnic
Teha seda, mida Hofmann ei suutnud ja minna edasi nauditav bike ride. Ideally somewhere with some pretty scenery — this year Bicycle Day falls on a sunny spring Saturday after all! Pack a picnic and cycle to a nature spot. Eat your favorite foods — you certainly don’t need to guzzle milk as Hofmann reportedly did during his first Bicycle Day trip! Just enjoy the nature around you. As Hofmann implored;
"Minge niitudele, minge aeda, minge metsa. Avage oma silmad!"

Mine psühhedeelsele reisile
Mõned inimesed otsustavad teha nii nagu Hofmann, minnes ise psühhedeelsele reisile. Mis võiks olla parem viis? Maagilised seened ja trühvlid on täiesti looduslikud ja neil on LSD-ga sarnane psühhedeelne toime. Järgige meie Reisijuht kõik, mida pead teadma.

Õpi midagi uut
Psühhedeelsed ained avavad meelt ja hoiavad meid uudishimulikena. Miks mitte veeta päev, et õppida psühhedeelsete ainete uurimise minevikust ja tulevikust? Üks parimaid viise, kuidas võidelda psühhedeelikute kohta käiva väärteabe vastu, on haridus. Uurige psühhedeelsete ainete teadust, ajalugu ja kasu ning jagage seda oma sõprade ja pereliikmetega. Meie blogi arhiiv ei ole halb koht alustamiseks!
Toetage psühhedeelset uurimistööd ja propageerimist
Miks mitte annetada mittetulundusühingule, näiteks Beckley Sihtasutus või Multidistsiplinaarne psühhedeelsete uuringute assotsiatsioon (MAPS)? Nii toetate otseselt psühhedeelsete uuringute edendamist ja positiivseid muutusi, mida need võivad maailmale tuua.
Head jalgrattapäeva!
This Bicycle Day, whether you trip, cycle, or simply marvel at the ingenuity of human curiosity, you are sure to have a wonderful time!
