Opium Law
Encyclopedia
The Opium Law is the section of the Dutch law
Law of the Netherlands
The Netherlands is a civil law country. Its laws are written and the application of customary law is exceptional. The role of case law is small in theory, although in practice it is impossible to understand the law in many fields without also taking into account the relevant case law...

Origin and history

In 1912, the First International Opium Conference took place in The Hague

, where agreements were made about the trade in opium
Opium
Opium is the dried latex obtained from the opium poppy . Opium contains up to 12% morphine, an alkaloid, which is frequently processed chemically to produce heroin for the illegal drug trade. The latex also includes codeine and non-narcotic alkaloids such as papaverine, thebaine and noscapine...

; this initiated the introduction of the Opium Law, which took place 7 years later. In 1919, the first Opium Law (later known as List I of the Opium Law) was introduced, and on 12 May 1928 the second Opium Law (later known as List II of the Opium Law) was introduced. The first Opium Law was created to regulate drugs with a high addiction or abuse factor, or that are physically harmful. As the name indicates the main reason for introduction was to regulate the Opium trade and later to control various other addictive drugs like morphine
Morphine
Morphine is a potent opiate analgesic medication and is considered to be the prototypical opioid. It was first isolated in 1804 by Friedrich Sertürner, first distributed by same in 1817, and first commercially sold by Merck in 1827, which at the time was a single small chemists' shop. It was more...

Except for the addition of new drugs to List I and II of the Opium Law, the Opium Law remained unchanged until 1976. After the rise of a new youth culture which revolved much around the use of drugs like cannabis
Cannabis

These three taxa are indigenous to Central Asia, and South Asia. Cannabis has long been used for fibre , for seed and seed oils, for medicinal purposes, and as a...

 being openly used, a change of law was needed by the government, to properly control all drugs, but with a clear definition between drugs with an unacceptable degree of addictiveness or physical harm (known as hard drugs), and drugs with an acceptable degree of addictiveness or physical harm (known as soft drugs). In 1976 these changes officially took effect, and the Opium Law was edited to include the new changes of law. In the same year, a decision was also made by the Dutch government not to prosecute cannabis and hashish dealers, under the condition that they didn't sell hard drugs, didn't advertise and they were only allowed to carry a certain amount of cannabis or hashish.

In 1980, the decision to not prosecute cannabis and hashish dealers, under certain conditions, was publicly announced by the Dutch government. Many people thereby concluded that this decision would also allow the sale in coffeeshop

Coffeeshops are establishments in the Netherlands where the sale of cannabis for personal consumption by the public is tolerated by the local authorities ....

s, and coffeeshops began selling cannabis and hashish. This led to an enormous rise in the number of coffeeshops in the 80's and 90's, and because of this, new regulations were demanded by the government to regulate the sale of cannabis products by coffeeshops. In 1996 the laws were changed again to include new regulations for coffeeshops. The terms coffeeshops had to follow were:
  • No advertisement
  • No hard drugs
  • No entrance to coffeeshops by persons under the age of 18
  • No sale of more than 5 grams of cannabis products per person, per day
  • Coffeeshops are not allowed to have more than 500 grams of cannabis in stock at any time


Since 1996, no new changes have been made to the Opium Law. New guidelines for coffeeshops have been made, but they are not covered by the Opium Law.

But in October 2011 the Dutch government proposed a change of the Opium law to the Dutch parliament. From spring 2012 will the change put cannabis with 15% THC

; this initiated the introduction of the Opium Law, which took place 7 years later. In 1919, the first Opium Law (later known as List I of the Opium Law) was introduced, and on 12 May 1928 the second Opium Law (later known as List II of the Opium Law) was introduced. The first Opium Law was created to regulate drugs with a high addiction or abuse factor, or that are physically harmful. As the name indicates the main reason for introduction was to regulate the Opium trade and later to control various other addictive drugs like morphine
Morphine
Morphine is a potent opiate analgesic medication and is considered to be the prototypical opioid.

 being openly used, a change of law was needed by the government, to properly control all drugs, but with a clear definition between drugs with an unacceptable degree of addictiveness or physical harm (known as hard drugs), and drugs with an acceptable degree of addictiveness or physical harm (known as soft drugs). In 1976 these changes officially took effect, and the Opium Law was edited to include the new changes of law. In the same year, a decision was also made by the Dutch government not to prosecute cannabis and hashish dealers, under the condition that they didn't sell hard drugs, didn't advertise and they were only allowed to carry a certain amount of cannabis or hashish.

In 1980, the decision to not prosecute cannabis and hashish dealers, under certain conditions, was publicly announced by the Dutch government. Many people thereby concluded that this decision would also allow the sale in coffeeshop

Coffeeshops are establishments in the Netherlands where the sale of cannabis for personal consumption by the public is tolerated by the local authorities ....

s, and coffeeshops began selling cannabis and hashish. This led to an enormous rise in the number of coffeeshops in the 80's and 90's, and because of this, new regulations were demanded by the government to regulate the sale of cannabis products by coffeeshops. In 1996 the laws were changed again to include new regulations for coffeeshops. The terms coffeeshops had to follow were:
  • No advertisement
  • No hard drugs
  • No entrance to coffeeshops by persons under the age of 18
  • No sale of more than 5 grams of cannabis products per person, per day
  • Coffeeshops are not allowed to have more than 500 grams of cannabis in stock at any time


Since 1996, no new changes have been made to the Opium Law. New guidelines for coffeeshops have been made, but they are not covered by the Opium Law.

But in October 2011 the Dutch government proposed a change of the Opium law to the Dutch parliament. From spring 2012 will the change put cannabis with 15% THC

 being openly used, a change of law was needed by the government, to properly control all drugs, but with a clear definition between drugs with an unacceptable degree of addictiveness or physical harm (known as hard drugs), and drugs with an acceptable degree of addictiveness or physical harm (known as soft drugs). In 1976 these changes officially took effect, and the Opium Law was edited to include the new changes of law. In the same year, a decision was also made by the Dutch government not to prosecute cannabis and hashish dealers, under the condition that they didn't sell hard drugs, didn't advertise and they were only allowed to carry a certain amount of cannabis or hashish.

In 1980, the decision to not prosecute cannabis and hashish dealers, under certain conditions, was publicly announced by the Dutch government. Many people thereby concluded that this decision would also allow the sale in coffeeshop

s, and coffeeshops began selling cannabis and hashish. This led to an enormous rise in the number of coffeeshops in the 80's and 90's, and because of this, new regulations were demanded by the government to regulate the sale of cannabis products by coffeeshops. In 1996 the laws were changed again to include new regulations for coffeeshops. The terms coffeeshops had to follow were:
  • No advertisement
  • No hard drugs
  • No entrance to coffeeshops by persons under the age of 18
  • No sale of more than 5 grams of cannabis products per person, per day
  • Coffeeshops are not allowed to have more than 500 grams of cannabis in stock at any time


Since 1996, no new changes have been made to the Opium Law. New guidelines for coffeeshops have been made, but they are not covered by the Opium Law.

But in October 2011 the Dutch government proposed a change of the Opium law to the Dutch parliament. From spring 2012 will the change put cannabis with 15% THC
