Wat is GHB?
GHB is een geurloze, stroperige vloeistof met een zoute smaak. GHB bestaat ook in poedervorm. De vloeistof zit in plastic buisjes met doorgaans een inhoud van 5 milliliter (ml). GHB is van oorsprong een narcosemiddel. GBL is een variant van GHB. GHB is een combinatie van GBL en natronloog. GBL is een agressief schoonmaakmiddel en natronloog wordt als gootsteenontstopper gebruikt.
GHB wordt wel eens ten onrechte vloeibare XTC (Liquid XTC, Liquid X, Liquid E) genoemd. Ten onrechte omdat de werkzame stof van XTC MDMA is en dus niets te maken heeft met GHB. Andere namen zijn G of ‘buisje’. Vanwege een mogelijke relatie met verkrachtingszaken wordt het ook wel ‘rape-drug’ genoemd.
GHB wordt gedronken. Het kan puur worden gedronken, maar vanwege de zoute smaak wordt het doorgaans vermengd met frisdrank, sap of water. Mixen met alcohol is gevaarlijk.
Samenstelling
Inhoud verpakking: 2 GHB testen 2 Flesjes met buffer vloeistof 2 Vitamine C teststrips 1 Kleurenkaart (GHB en Vitamine C)
Gebruik
GHB-Check test op de aanwezigheid van GHB in urine (of andere vloeistoffen) door middel van een biochemische reactie in de test cassette. Na toedienen van de benodigde druppels urine, zal er in de test cassette een reactie gaan plaatsvinden. Vervolgens kan het resultaat worden afgelezen tussen de 5 en 10 minuten. De hoeveelheid GHB aangetoond in het monster kan worden bepaald met de meegeleverde kleurenkaart. Hoge concentraties GHB zullen zorgen voor een donker paarse verkleuring van de Testlijn op de cassette.
GHB (van nature ook in zeer lage concentraties aanwezig in het menselijk lichaam) is niet onbeperkt aantoonbaar in de urine. Indien er echter een vermoeden bestaat van GHB gebruik, kan de urine (bij een temperatuur tussen 2 en 8 graden Celsius) nog 48 uur voordat er getest kan worden, worden bewaard. De urine moet voor gebruik dan wel weer op kamertemperatuur worden gebracht. Urinemonsters kunnen ook nog langer worden opgeslagen, echter dan moeten deze monsters worden ingevroren (- 20 graden Celsius).
Naast urine, kunnen ook andere vloeistoffen met de test worden getest op de aanwezigheid van GHB. Hoge concentraties van alcohol echter, kunnen mogelijk ook leiden tot fout positieve uitslagen.

Be ready to question everything and everyone…
Format: Kindle
We Used to Live Here definitely nails the creeping sense of dread and paranoia throughout the story. I constantly questioned whether Eve was truly unraveling or if she was the only person actually sensing danger, and the added news articles, interviews, and scientific discussions throughout the book made the atmosphere even more unsettling. I also connected with Eve’s struggles surrounding anxiety, people-pleasing, and past religious experiences, which added an emotional layer to the horror for me.
That said, the pacing felt super uneven. Most of the story takes place over only a couple of days, but it dragged at times and honestly felt like it would work better as a movie than a book. Things finally picked up around the 70% mark, but the ending left me wanting much more explanation and payoff than we as the readers received.
Overall, this was an eerie, anxiety-inducing read with a fantastic atmosphere, even if the execution didn’t fully land for me.

Format: Paperback
I liked the pace, the story and the characters. Sadly I found it at the end a bit confusing. I think the book needed more edition work. Otherway, it is a recommendable book if you want horror with a bit of science fiction. Be advised you'll need to use your imagination to understand certain pasages.

Not even a good read. Pass it.
Format: Paperback
Unfortunately, this book was basically a whole lot of nothing. It was not what I was hoping for, which was on the edge of your seat scary. It was not even alittle scary. Left me with unanswered questions and confused. Sorry..I did not like this book at all.

Easy to read and fall in love with
Format: Hardcover
one of those books that feels less like a story and more like an experience. Ray Bradbury captures the magic of summer, childhood, and all the little things in life we take for granted. I loved the way it blended nostalgia with those bittersweet moments of growing up. It’s slow at times, but that’s the beauty of it — it makes you stop and notice the small details, just like the characters do.
For me, it felt like stepping back into a simpler time, but with all the emotions and lessons that still matter today. It’s warm, reflective, and beautiful. A book you don’t just read — you feel.

Ray Bradbury
August 22nd 1922 - June 5th, 2012
When Ray Bradbury died reactions came from everywhere including from President Obama. Surprising to me, few mentioned the one of his works that meant so much to me and affected my life so deeply. While he was most known to the general public for his science fiction, I found his mostly autobiographical novel Dandelion Wine to be the most impactful. At the same time it best illustrated Bradbury’s incredible command of the language, his ability to stir the imagination, and the way in which he could open windows on life.
I couldn’t count the number of times I would reread a single sentence and become overwhelmed with admiration and envy at how he used words to create images in the mind’s eye. All this was particularly on display in Dandelion Wine and its sequel, Farewell Summer. For Bradbury, it couldn’t be just water. “Nothing else would do but the pure waters which had been summoned from the lakes far away and the sweet fields of grassy dew on early morning, lifted to the open sky, carried in laundered clusters nine hundred miles, brushed with wind, electrified with high voltage, and condensed upon cool air. This water, falling, raining, gathered yet more of the heavens in its crystals. Taking something of the east wind and the west wind and the north wind and the south, the water made rain and the rain, within this hour of rituals, would be well on its way to wine.”
Essentially, Dandelion Wine is the story of a summer in the life of a twelve year old boy as he comes to understand what it means to be alive. But it is also a time capsule for the year 1928 of life in a small town when everyone’s world was much smaller and more compact. There is horror, love, comedy, wonder, nostalgia, and human relations. Bradbury could find unique ways to describe them all.
I first read Dandelion Wine in 1957 when I wasn’t much older than Douglas Spaulding, the central character. It helped me put life in perspective as I was leaving high school. I read it the second time in the early ‘80s when I introduced my daughter to it. Kelly and I sat on our front porch swing one warm summer evening and I read aloud to her the story of Bill Forrester and Helen Loomis. It was all I could do to finish it and when I did we both had tears streaming down our cheeks. Such was the power of imagination and Bradbury’s ability to stroke it to life using just words.
I read it the third time in preparation for reading the sequel, Farewell Summer, written 55 years after Dandelion Wine. Like a fine wine, it had only gotten better with age. Appropriately, Farewell Summer was given to me by Kelly and I read it on summer’s eve 2012. It was the perfect beginning for yet another summer.
In both books the ravine in Green Town, Illinois, based on Waukegan, Illinois where Bradbury grew up was a central feature. I couldn’t resist going to Googlearth to see if the ravine was real. It was. And, it is still there even after Waukegan had changed from a small town to a satellite of Chicago. I was pleased to simply find I could locate it. But when I zoomed in and highlighted the little tree symbol I found the ravine is now Ray Bradbury Park. Perfect!
