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 \u2014 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.\u00a0<\/strong><\/p>\n\n\n\n

Qui \u00e9tait Albert Hofmann ?<\/h2>\n\n\n\n

Albert Hofmann \u00e9tait un chimiste suisse, surtout connu comme le \"p\u00e8re\" du di\u00e9thylamide de l'acide lysergique. lui-m\u00eame<\/em> est surtout connu sous le nom de LSD. Il a effectu\u00e9 des travaux novateurs sur les propri\u00e9t\u00e9s du LSD et d'autres psych\u00e9d\u00e9liques, tels que le psilocybine<\/a> des champignons magiques. Ses recherches ont permis de mieux comprendre la conscience humaine et ont eu un impact sur les domaines des neurosciences, de la pharmacologie et de la psychologie. Elle a \u00e9galement \u00e9t\u00e9 le catalyseur de l'int\u00e9r\u00eat mondial pour les psych\u00e9d\u00e9liques. <\/p>\n\n\n\n

Qu'est-ce que le LSD ?<\/h3>\n\n\n\n

Lysergic acid diethylamide, is a psychedelic substance synthesized from a fungus called ergot<\/a>. It is renowned for its ability to cause profound changes in perception, thought patterns, and mood. It is categorized as a hallucinogen<\/a> due to the trippy visual effects it can induce. However, these effects can vary based on dosage, setting, and the individual user.\u00a0<\/p>\n\n\n\n

Qu'en est-il de l'ergot ?<\/h4>\n\n\n\n

Ergot is a type of fungus that grows on grains such as rye. Its effects, both medicinal and toxic, have been enregistr\u00e9es au cours de l'histoire<\/a>. 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.\u00a0<\/p>\n\n\n\n

It\u2019s 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 <\/em>que les Grecs de l'Antiquit\u00e9 buvaient lors de la Myst\u00e8res \u00e9leusiniens<\/a>. However, more often than not, ergot was accidentally ingested, as it grew on grains used to make bread \u2014 a staple food throughout much of human history. This could cause symptoms ranging from nausea, to gangrene, to death.\u00a0<\/p>\n\n\n\n

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.\u00a0<\/p>\n\n\n\n

Quels sont les effets du LSD ?<\/h2>\n\n\n\n

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 \u2018trip\u2019, can last from 6 to 12 hours, depending on various factors, such as dosage.\u00a0 <\/p>\n\n\n\n

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.\u00a0<\/p>\n\n\n\n

Pourquoi la \"Journ\u00e9e de la bicyclette\" ?<\/h2>\n\n\n\n

So, why Bicycle Day? Why not \u2018LSD Day\u2019? <\/p>\n\n\n\n

Well, with LSD up until pretty recently being designated ‘dangerous’, not to mention illegal by the powers-that-be, that title probably wouldn\u2019t have flown. So, to get past the censors, Bicycle Day cleverly refers to Hofmann\u2019s iconic bike ride he took after ingesting LSD on April 19th, 1943. It started off as a bit of a codename \u2014 if you conna\u00eetre <\/em>puis vous conna\u00eetre <\/em>????. <\/em>Il ne faut pas confondre cette journ\u00e9e avec la Journ\u00e9e mondiale de la bicyclette, qui a lieu le 3 juin de chaque ann\u00e9e.\u00a0<\/p>\n\n\n\n

But what was so special about this infamous bike ride?<\/p>\n\n\n\n

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 avril)<\/em>C'est en effet la premi\u00e8re fois que le LSD est consomm\u00e9 dans un pays \u00e9tranger. \u00e0 dessein.\u00a0<\/strong><\/p>\n\n\n\n

Apr\u00e8s avoir ing\u00e9r\u00e9 le LSD (and not yet knowing that 250 micrograms is a very high dose!) <\/em>Hofmann began to feel the effects quickly \u2014 within 40 minutes.\u00a0 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.\u00a0<\/p>\n\n\n\n

\"Shrooma<\/figure>\n\n\n\n

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!<\/p>\n\n\n\n

Le voyage de Hofmann<\/h3>\n\n\n\n

Tout au long du trajet, Hofmann a ressenti d'intenses effets psych\u00e9d\u00e9liques. Sa perception du monde a \u00e9t\u00e9 consid\u00e9rablement modifi\u00e9e, comme si sa conscience avait \u00e9t\u00e9 s\u00e9par\u00e9e de son corps. Il a d\u00e9clar\u00e9 avoir eu l'impression de flotter au-dessus du sol. Tout ce qu'il voyait \u00e9tait en mouvement, les couleurs et les formes se d\u00e9pla\u00e7ant et vacillant devant lui. <\/p>\n\n\n\n

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 (en dehors des pupilles dilat\u00e9es et de sa confusion apparente) <\/em>he was able to relax, and lean in, to what he was experiencing.<\/p>\n\n\n\n

\"A

As the effects of the drug wore off, Hofmann began to realize LSD\u2019s 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;<\/p>\n\n\n\n

\"Gr\u00e2ce \u00e0 mon exp\u00e9rience du LSD et \u00e0 ma nouvelle image de la r\u00e9alit\u00e9, j'ai pris conscience de l'\u00e9merveillement de la cr\u00e9ation, de la magnificence de la nature et du r\u00e8gne animal et v\u00e9g\u00e9tal. Je suis devenu tr\u00e8s sensible \u00e0 ce qui va arriver \u00e0 tout cela et \u00e0 chacun d'entre nous\".<\/strong><\/em><\/p>\n\n\n\n

L'exploration courageuse de l'inconnu par Hofmann s'inscrit dans la grande lign\u00e9e des scientifiques et des chercheurs qui font des exp\u00e9riences sur eux-m\u00eames. Son exp\u00e9rience a jet\u00e9 les bases d'une nouvelle \u00e8re d'\u00e9tudes, qui a eu un impact sur tous les domaines de la culture. <\/p>\n\n\n\n

Quand la Journ\u00e9e de la bicyclette a-t-elle \u00e9t\u00e9 c\u00e9l\u00e9br\u00e9e pour la premi\u00e8re fois ?<\/h2>\n\n\n\n

La Journ\u00e9e de la bicyclette a \u00e9t\u00e9 lanc\u00e9e en 1985 par un professeur de l'universit\u00e9 de l'Illinois du Nord, le Dr Thomas B. Roberts. Cette manifestation, qui \u00e9tait \u00e0 l'origine un \u00e9v\u00e9nement local, a gagn\u00e9 en popularit\u00e9 au fil des ans. Elle est devenue un refuge pour un large \u00e9ventail de personnes int\u00e9ress\u00e9es par les psych\u00e9d\u00e9liques, l'exploration de l'esprit, la r\u00e9forme de la politique en mati\u00e8re de drogues, etc. Aujourd'hui, des c\u00e9l\u00e9brations ont lieu dans le monde entier. <\/p>\n\n\n\n
