Alcohol
The consumption of alcohol is prohibited in the majority of public places in the city centre but you are naturally welcome to visit one Amsterdam's many bars. Never combine drugs with alcohol. For more information about health matters in the city, contact the Public Health Service of Amsterdam.
For serious drug and alcohol-related emergencies, seek immediate medical assistance. In the Netherlands, you cannot be prosecuted for offences related to taking drugs subsequent to visiting the emergency department.
Drugs
Purchasing and smoking soft drugs such as cannabis is only permitted in coffeeshops; individuals (aged 18 and above) are permitted to purchase a maximum of five grammes a day. Purchasing or selling hard drugs such as ecstasy (MDMA), heroin and cocaine is illegal. Visitors are advised to ignore street dealers, as they can become aggressive and often sell fake or unsafe drugs.
If you are planning on trying soft drugs, research the subject in advance. Exercise caution and never combine drugs with alcohol. The Jellinek website is a valuable source of information
Prostitution
Window brothels, sex clubs and escort agencies can operate legally if they have been granted the relevant permits by the City of Amsterdam. Everyone is welcome to visit the Red Light District, although if touring the area, be respectful and don't take photographs or record videos. If you decide to visit a prostitute, practice safe sex and never deal with prostitutes under 21 years of age. Forced prostitution is an extremely serious crime. Remain vigilant to indications of forced prostitution (such as anxiety, bruises or willingness to have intercourse without a condom) and report any suspicions to the police by calling 0900-8844 /+31 343 578 844 or anonymously on 0800-7000 (from a Dutch phone).
