Here's an old post on this very subject.
"I'm glad you all know better than students what is in their interest when it comes to drug laws.
Massive decriminalisation and addict treatment in portugal has reduced addictgion rates and probably lowered use. The money saved on enforcement can be thrown at treatment - even without regulation and taxation at the point of sale..."
Not really true.
“Portugal keeps on being the country with the most cases of injected drug related AIDS (85 new cases per one million of citizens in 2005, while the majority of other EU countries do not exceed 5 cases per million) and the only one registering a recent increase. 36 more cases per one million of citizens were estimated in 2005 comparatively to 2004, when only 30 were referred ” (EMCDDA - November 2007).
- Since the implementation of decriminalization in Portugal, the number of homicides related to drug use has increased 40%. "Portugal was the only European country to show a significant increase in homicides between 2001 and 2006."
(WDR - World Drug Report, 2009)
"With 219 deaths by drug 'overdose' a year, Portugal has one of the worst records, reporting more than one death every two days. Along with Greece, Austria and Finland, Portugal is one of the countries that recorded an increase in drug overdose by over 30% in 2005".
(EMCDDA – November 2007)
The number of deceased individuals that tested positive results for drugs (314) at the Portuguese Institute of Forensic Medicine in 2007 registered a 45% raise climbing fiercely after 2006 (216). This represents the highest numbers since 2001 – roughly one death per day - therefore reinforcing the growth of the drug trend since 2005.

- “Behind Luxembourg, Portugal is the European country with the highest rate of consistent drug users and IV heroin dependents”.
(Portuguese Drug Situation Annual Report, 2006)
- Between 2001 and 2007, drug use increased 4.2%, while the percentage of people who have used drugs (at least once) in life, multiplied from 7.8% to 12%. The following statistics are reported:
Cannabis: from 12.4% to 17%
Cocaine: from 1.3% to 2.8%
Heroine: from 0.7% to 1.1%
Ecstasy: from 0.7% to 1.3%.
(Report of Portuguese IDT 2008)
- “There remains a notorious growing consumption of cocaine in Portugal, although not as severe as that which is verifiable in Spain. The increase in consumption of cocaine is extremely problematic.”
(Wolfgang Gotz, EMCDDA Director - Lisbon, May 2009)
- “While amphetamines and cocaine consumption rates have doubled in Portugal, cocaine drug seizures have increased sevenfold between 2001 and 2006, the sixth highest in the world”.

Also, for a case closer to home, marijuana-related crime has risen significantly since 'de-criminalization' was implemented in Massachusetts.
