A tourist doctor covers non-emergencies
For non-emergencies there is a tourist-focused doctor service that runs an ADE service each year with clinic and hotel visits. Confirm hours and insurance coverage when you book, since several similarly named practices exist.
Edibles hit slow, go low
Space cakes and edibles take 30 to 90 minutes to hit. Eat a half or a quarter, wait at least 45 minutes, and never redose because you do not feel it yet. Dutch edibles run strong, so do not stack one before a headline set.
Coffeeshop basics
For visitors: 18+ with passport, a 5g per-person limit, many shops cash-only, and no alcohol alongside cannabis. A coffeeshop sells weed, a cafe sells coffee, and walking into the wrong one is the classic tourist tell.
Street smoking is banned in the center
Smoking weed on the street is banned in the Red Light District, Dam Square, Damrak and Nieuwmarkt, with a 100 euro fine on the books. Smoke inside the coffeeshop or at your place, and never cycle stoned.
Never buy from strangers
The one rule everyone agrees on: never buy anything off a stranger on the street or in a queue. What is sold as one thing has turned out to be another, with fatal results. If someone in your crew starts feeling wrong, get help immediately: venue security and first aid put safety ahead of enforcement, and calling 112 has never got anyone arrested.
Harm reduction, use it the week before
Amsterdam's free-spirited reputation comes with genuinely great harm-reduction services, and the insiders use them the week before the festival, when the timing works.
Bring sealed electrolytes
Fan wisdom, not a rule: bring electrolyte sachets but keep them factory-sealed, since security tends to let unopened wrappers through, and refill water at the taps. Door practices vary by venue and are unpublished, so treat this as what the fam does.
Big rooms, keep it zipped
Big rooms, big energy: leave the chains and watches at home and keep your phone zipped up front, especially in the crush. If the crowd suddenly moves, drift calmly to the edges with your crew. If anything goes missing, tell venue security right away, that is how phones actually come home.
The canal-side walk home
For the canal-side walk home: hit the bathroom before you leave the club, and keep your crew on the building side of the path. The canals are beautiful and best admired from a meter back.
Keep your drink covered
Keep your drink in hand or covered and never accept an opened one. If someone feels far drunker than they drank, go to venue first aid right away and ask for spiking testing that night, the evidence window closes by morning.
Watch for the friendly distraction
In the busy districts, thieves often work in pairs: one strikes up close conversation, asks directions or says you dropped something, while the other takes what is loose. Keep nothing in back or open pockets, and swing a zipped crossbody bag to your front in queues and crowds.
